This guide has been created for the 1966 Studebaker Daytona Sports Sedan. Follow this link if you are looking for information on the 1965 Sports Sedan. The 1966 Daytona Sports Sedan was the last 2-door Daytona model produced by Studebaker before the company ended vehicle production in March 1966. The 1966 Sports Sedan model was produced in very low numbers relative to other models due to its short production run, and as a result is a highly collectable vehicle. 

As the Sports Sedan was introduced after Studebaker's decision to end manufacturing in the US, all Sports Sedans were produced in the Ontario plant in Canada, and made use of a McKinnon 283ci 'Thunderbolt' engine, or the 194ci or 230ci 6-cylinder 'Skybolt' motor which were built at GM's St Catherines engine plant. This guide outlines a number of features relevant to identifying an authentic vehicle, including exterior, interior and mechanical features, along with details of the relevant engine and body codes. 

Number built: 873 total (620 V8, 253 6-cylinder) 

Period of Manufacture: August 1965 - March 1966. All cars were built in the Hamilton, Ontario factory in Canada during this period.

It is believed that approximately 12 of the last 1965 Sports Sedans were converted to 1966 models. These vehicles had a new chassis number assigned over the 1965 number on their build sheet, and may have several traces of a 1965 vehicle's specifications. The last 1965 model built is believed to be serial number C-520704, and the owner of this vehicle confirmed that their car was converted to a 1966 model. If you know of or own a car with a similar serial number close to this, please contact us to confirm the specification of your car so we can confirm this information. Classic Register also maintains an informal register of Sports Sedans here on the site. If you own a Sports Sedan, please sign-up and add your vehicle to the register.

1. Exterior features – 1966 Studebaker Daytona Sports Sedan
  • All Sports Sedans were based on the 2-door sedan body (Sports sedans always had a B-pillar, and were not available as a pillarless hard-top).
  • A white or black vinyl roof could be specified depending on the vehicle's paint colour, with stainless steel finishing trim at the base of the C-pillar. The 1966 model did not featured any emblem on the C-pillar as was applied to the 1965 model.
  • Cursive 'Daytona' badging was applied to the front mudguards in front of the wheel arch, and below the right rear tail light.
  • A Hawk emblem badge with engine capacity details (194, 230 or 283) was applied to the front fenders behind the wheel arch.
  • Single exhaust was standard (exiting on the RHS). Twin exhausts were optional (depending on where the car was bought) which exit on the outer sides of the rear central bumper overriders.
  • Rear bumper overriders were applied as standard on either side of number plate area. Additional front and rear over-riders could be optioned, or applied aftermarket.
  • 4.5 x 15 inch steel wheels were fitted, with stainless steel Hawk-emblem hubcaps. The steel wheels were originally painted off-white, and were several shades lighter than 1962-1963 model Studebaker wheels.
  • Tyres originally applied were Firestone Deluxe Champion P195/75R15, which had a thin whitewall of approximately 1 inch
  • Single dual-beam headlights replaced the quad-light front end in 1966, and included a facelifted front grille design with central Hawk emblem.
  • Vented rear tail lamps formed part of the Studebaker 'Refreshair' system of 1966. Tail lights on early 1966 cars were painted the vehicle's body colour, however, at some point they changed to a chrome finish (dates still to be confirmed).
  • The chrome strip running between the tail lamps was not applied to 1966 model cars, and a new stainless steel trim was applied below the rear trunk lid, and ran between two newly applied reverse lamps. The 'Studebaker' and 'Daytona' badging was applied on top of this trim.
  • The stainless steel side moulding trim applied was thinner than that used on the 1965 model Daytona, and was moved to the lower half of the body, running between the wheel arches.
  • External side mirrors were not compulsory in some states, and most vehicles were fitted with a circular Stratoline mirror on at least the driver's side.
2. Interior Features – 1966 Studebaker Daytona Sports Sedan:
  • Vinyl interior trim colour options included:
    • Champagne White
    • Tahitian Red
    • Black
  • Sports Sedans were fitted standard with front bucket seats, a rear bench seat and an optional centre console. The front bucket seats had ash-trays mounted on the backs. A front bench seat with split-back could also be optioned.
  • Seats were vinyl covered with backs and squabs having large pleated sections (as differentiated from the even pleats and buttoned tufting on 1965 vehicles).
  • Door cards were revised for 1966, with the lower 40% carpeted, with a woodgrain trim strip running vertically through the window crank area and housing a small Hawk emblem. The upper half of the door card was trimmed in vinyl matching the seat colour, and had a vertical pleat pattern, and a small arm-rest. The rear side cards were trimmed in the same vertical pleat vinyl pattern as the front doors, had a small arm rest, but did not include the woodgrain trim through the rear window crank.
  • The 1966 Daytona dashboard had woodgrain trim strip that extended across the fascia and applied to the instrument panel surround. Despite interior trim colour, all dashboards we have sighted on Sports Sedans have been black.
  • Triple instrument cluster display (instrumentation included fuel, temperature, oil and Amps (left gauge), speed (centre) and an optional clock (right). On cars not fitted with a clock face in the right instrument position, a blank instrument was installed the text "Studebaker Corporation" or "Studebaker of Canada" circling the instrument face (see images for examples).
  • Carpet colour was matched to the interior trim, and the heel pads in the front had the lazs "S" emblems in them (1966 being the only year these were applied). 
  • The roof lining was cream on all 1966 Sports Sedans. 
  • The dashboard incorporated a push-button Studebaker radio, and air-conditioning was optional. The air conditioning unit consisted of an under-dash mounted system, which had printed on the front "Air Conditioned by Studebaker". Cars fitted with this system may have also had a sticker on the rear windscreen stating "Air Conditioned by Studebaker", although this is more commonly sighted on 1965 cars.
  • Pop up mirror in glove box, with cup tray built into the lid.
  • The sun-visor clips on the 1966 model are aluminium (as opposed to white plastic as applied to the 1965 model).
  • Vinyl trunk matt and spare wheel cover.
  • All 1966 Sports Sedans were fitted with a black steering wheel.

3. Factory Paint Colours / Codes – 1966 Studebaker Daytona Sports Sedan

The following tables outline the colours available on the 1966 Studebaker Daytona Sports Sedan, and these were available with either a black or white vinyl roof.

The official paint colour options for the 1966 Sports Sedan are listed in this first table:

Paint colour Studebaker code Ditzler code
Niagra Blue Mist P-6481 C 13270
Timberline Turquoise P-6482 C 43591
Yellow-knife Gold  P-6483 C  22750
Mount Royal Red P-6484 C 71559
Arctic White P-6485 C 8628
Black P-6486 C 9000
Richelieu Blue P-6487 C  13112
Algonquin Green P-6488 C 43592


Throughout our research, we have sighted several cars and spoken to several owners who have claimed additional colours were available on the 1966 Sports Sedan which were not listed on the official 1966 paint chart. We have since been advised by the administrator of the 1966 Daytona register that several spring colours were introduced, including Highland Red and Plum.  These colours below are what we had previously thought were sighted on 1966 model cars, however, are believed to not be correct. This section will be updated shortly.

Paint colour Studebaker code Ditzler code
Sienna Red P-6478 C 71513
Strato Blue P-6413 C 12878
Moonlight Silver P-6416 C 32383

*These colours are based on assumptions from a couple of 1966 models we have sighted that appear to be a close match to these earlier Studebaker colours.



4. Chassis Number / VIN and Body Tag – Studebaker Daytona Sports Sedan

Vehicle identification number (VIN):

The 1966 Sports Sedan vehicle identification numbers commenced at C530001. It is important to note, however, that VIN numbers of this style were also applied to other 1966 Daytona body styles, as well as 1966 Commander models. Therefore, this number on its own does not necessarily confirm with certainty that the vehicle is a Sports Sedan. Other features as noted throughout this guide should be referenced to confirm authenticity, along with a vehicle's original build sheet.

Location of chassis plate / VIN plate:

The VIN plate on 1965 and 1966 cars is riveted (using rosette rivets) to the inside post of the driver’s door, between the hinges. See the images for an example.


Body tag details:

The body tags provide information with respect to the year, engine type, and unique body number.

There were two body tags applied:

  • Tag 1: "V-F8" = 2-door 283ci V8 Sports Sedan  /  "S-F82-door 194ci or 230ci 6-cylinder Sports Sedan.
  • Tag 2: This 4 digit code is the vehicle's unique body number.


The body tags were screwed onto the vehicle's firewall just below the heater air-filter (as shown in the images).


Original order / build sheets (production order):

The most accurate way to confirm a vehicle's authenticity and original specifications is to order an original build sheet from the Studebaker National museum. You will need to provide the vehicle's serial number and model to order one of these, and the sheet will confirm all the relevant serial numbers as the car was built, the trim level, paint color, options from the factory, key codes, etc. This link will take you to the order form on the Studebaker National Museum website. We have provided an anonymised example in the images to show you the information that this build sheet will provide.

5. Engine Serial Number – Studebaker Daytona Sports Sedan

283CI V8 engine number:

The 283CI engine fitted to the 1966 Sports Sedan will have a serial number of 776,400,001 or higher.

The serial number is located on the top front passenger side of the engine block. You will see a flat area, with the serial number punched in. The number is displayed with the "77" spaced slightly apart from the remaining serial number digits.

As the McKinnon engine plant also produced engines for other GM brands from this plant, the batches of engines allocated to Studebaker were not all consecutive, and therefore large 'gaps' in serial number data exists from one car to the next. Further, unlike other GM 283 engines, the McKinnon blocks used in Studebakers did not have a foundry code preceding the engine serial number. For example, the St Catherines McKinnon plant would usually have "K" applied prior to the serial number, but such plant ID codes are absent on the Studebaker engines we have viewed so far. We have relied on a small sample of engine numbers to make this conclusion, so if readers have any further information, please contact us.

See section 7 of this guide for further details with respect to the 283 McKinnon engines.


194ci or 230ci 6-cylinder engine number:

The engine number applicable to the 194ci or 230ci engine will be located on the passenger side of the engine block, stamped into a flat area directly behind the distributor. Unfortunately we are not aware of the commencing engine number on the 230ci or 194ci engines, and therefore an original build sheet would need to be ordered to confirm a vehicle's correct engine.


6. Engine Block and Cylinder Head Casting Numbers – 1966 Studebaker Daytona Sports Sedan

V8 engine block casting numbers:

The 283 McKinnon block will have a factory casting number located on a ledge at the rear of the block on the driver's side. The ledge area forms the flange between the block and transmission housing. This casting number should be 3849852, which according to Chevrolet records, identifies the block as a 1964-1968 Small block 283CI, 195 - 220 HP (2bbl and 4bbl models). This casting code was applied to Chevrolet engines from other USA based engine foundries, and therefore may not necessarily confirm the engine was produced at the McKinnon foundry.


V8 cylinder head casting marks and numbers:

Engine cylinder head casting number should be “3795896” or “3884520”. This number corresponds with 60cc heads, and can be found on the side of the head, between the valve springs, under the valve covers. These heads were distributed to Studebaker with the 283 block, and also had “Canada” cast into the head. Images of these markings have been provided where possible.


At this stage we have not confirmed casting numbers or other identifying marks for the 6-cylinder motors available with the Sports Sedan. If readers have any relevant information, please contact us so we can improve this section.

7. McKinnon 283 V8 rumours – 1966 Studebaker Daytona Sports Sedan:

The 283ci V8 engine has been the subject of extensive debate among Studebaker enthusiasts, and many rumours exist with respect to its source and precise specification.

It is generally agreed that the Sports Sedan engine was manufactured by GM subsidiary McKinnon Industries, in St Catherines, Ontario. The same plant is believed to have supplied 283 engines used in Canadian built Pontiacs and other GM vehicles. Many people over the years have suggested that these McKinnon V8 engines were unique when compared to other 283 engines built in other GM plants throughout the USA. It is often suggested that the McKinnon engines had forged steel crankshafts and con-rods, cylinder heads designed for a 4-barrel carburettor, heavy duty timing chains, valve rotators, high nickel content engine blocks/heads and thicker cylinder walls. There is also a rumour that not all 283 engines fitted to Studebakers came from the McKinnon plant, and that some would have been sourced from other US foundries if supply was insufficient. In dissent, others have argued that these specifications are incorrect, or that all 283 engines of this period had features such as forged steel crankshafts (among other items), and therefore the engines are no different to other GM equivalents.

Despite significant debate on this topic and much hearsay evidence from both sides of the fence, we have not seen any direct comparison done between the part numbers and specifications within a McKinnon engine, versus other 283 engines produced by other GM plants during the same era. As such, we cannot make any solid conclusion with respect to this engine being unique. A pull-down comparison of each engine would be necessary to put these arguments to rest once and for all.

As in the previous sections of this guide, several owners of these McKinnon engines have confirmed Studebaker’s 283 engine serial numbers and casting codes on the head and engine block. In the absence of an original build sheet, the additional characteristics listed below are also applicable to the 283ci engines used in Studebakers:

  1. “CANADA” is cast into the engine head, the intake manifold and on the plugs and air filter.
  2. Crankshaft part number is “3876784”.
  3. Engine block and heads were painted matt black.
  4. Early valve covers were non-embossed and painted Studebaker yellow. However, from some point during the 1965 model year (specific date unknown), all valve covers were painted matt black. A decal was applied to these reading “Studebaker Thunderbolt V8”.
  5. Studebaker fitted engines had a revised fuel pump design (the original GM design interfered with Studebaker’s front cross-member).
  6. Unlike other 283 GM engines, the Studebaker engines we have sampled have not had an engine foundry code confirming their plant of origin. This is usually a code that is stamped in front of the engine serial number. For the St Catherines plant engines, we expected to see code “K”, however, it seems that the Studebaker blocks were ‘anonymised’ in this respect.
8. Mechanical Features – 1966 Studebaker Daytona Sports Sedan:
  • The majority of 1966 Daytona Sports Sedans were fitted with a 283 cubic inch McKinnon 'Thunderbolt' V8 motor (60cc chamber), producing 195hp @ 4800 RPM.
  • Two GM 6-cylinder power plants were also available in the Daytona Sports Sedan. This included a 194 cubic inch 6-cylinder 'Skybolt' engine (producing 120hp) or a 230 cubic inch 'Skybolt engine' (producing 140hp).
  • As noted in the V8 engine discussion earlier in this guide, the Studebaker engines have non-embossed valve covers. The V8 valve covers had “Studebaker Thunderbolt V8" decals applied, and the 6-cylinder models had “Studebaker Skybolt” decals applied. All rocker covers / valve covers on 1966 model cars were painted black. The engine block and heads were also painted matt black.
  • Single Rochester carburetor (2GV, 2 barrel). 
  • Checker and Jeep bellhousing with 3 speed (column-shift) Borg Warner transmission, and 3.07:1 diff ratio.
  • Optional 11 inch front disc brakes with Dunlop-Bendix calipers.
  • Rear drum brakes were 10 inch, as were the front drum brakes if the vehicle was not disc brake equipped. Drum brakes were finned for temperature control / reduced fade.
  • Dual circuit brakes were fitted as standard.
  • Independent front suspension (coil springs) and live rear axle (leaf springs).
  • 4.5 X 15 inch steel wheels with polished aluminium hubcaps (with central hawk badge) and P195/75R15 tyres. Firestone Deluxe Champion tires were originally applied with a thin white-wall.
  • Prestolite alternators were originally fitted to the McKinnon engines, and alternative fuel pumps were fitted to allow clearance of Studebaker’s chassis cross-member.
  • A single exhaust was standard. Stock exhaust and headers were a 2 inch system (the ram-horn manifold only allows for a 2 inch outlet). The original mufflers applied to the exhaust system were aluminium.
  • Transistor ignition system was fitted as standard equipment (as applied to all 66 Studebakers). Cars had a small decal applied to the rear window designating this.
  • Twin speed wipers were standard on all models.
