This guide has been created for the 1965 Studebaker Daytona Sports Sedan. Follow this link for information on the later 1966 Studebaker Sports Sedan. The Sports Sedan was Studebaker's only 2-door 'Daytona' model available for the 1965 year, produced alongside the Daytona 4-door sedan and Wagonaire models. The Sports Sedan was produced in relatively low numbers and received a number of unique features compared to other vehicle's in the 1965 range, making it one of the most desirable late model Studebakers. 

As the Sports Sedans were introduced after Studebaker's decision to end manufacturing in the US, Sports Sedans were all produced in the Ontario plant in Canada, and made use of a McKinnon 283ci 'Thunderbolt' engine which was built at GM's St Catherines engine plant. Aside from one vehicle, all Sports Sedans for the 1965 year were V8 powered. One car was fitted with Chevrolet's 194ci 6-cylinder motor. 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: 1,627 Daytona Sports Sedans were produced for the 1965 year: (1,626 V8, one 6-cylinder).

Period of Manufacture: September 1964 - June 1965.

It is believed that approximately 12 of the last 1965 Sports Sedans were built as 1965 vehicles, but 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. 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 – 1965 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 pillar-less hard-top).
  • A white or black vinyl roof could be specified depending on the vehicle's paint colour, with aluminium finishing trim at the base of the C-pillar. The vinyl roof also featured a V8 emblem part way up the C-pillar (this was later dropped on the 1966 Sports Sedans).
  • Cursive aluminium 'Daytona' badging was applied to the front mudguards in front of the wheel arch, and below the left rear tail light. The red-white-blue Studebaker badge was also 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.
  • Vehicles optioned with air-conditioning could receive an 'Air conditioned by Studebaker' sticker on the rear windshield.
  • 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 polished aluminium hubcaps (same as applied to the 1964 model). 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.
  • The same quad headlight front grille and rear tail lights as applied to the 1964 model were retained for the 1965 model.
  • Side aluminium trim running along the upper side of the car doors and mudguards (This trim was the same as applied to the 1964 Daytona. The later 1966 model cars had a thinner band applied lower on the body).
  • 1965 cars also lost the 'STUDEBAKER' lettering across the trunk lid, which was applied to 1964 models. The 1965 model had a single chrome strip lining up with the centre of the tail lights, but lost the two thinner strips which lined up with the top and base of the tail lights as applied to 1964 models. The 1965 model gained an additional chrome trim over the rear body line which linked to the rear fender body crease (this was absent on 1964 model cars).
2. Interior Features – 1965 Studebaker Daytona Sports Sedan:
  • Sports Sedans were fitted with front bucket seats, a rear bench seat and an optional centre console. The front bucket seats had ash-trays mounted on the backs. As standard, these seats did not recline, but a reclining feature was an option.
  • A buttoned/tufted vinyl fabric was applied to the seats. The front bucket seats had 6 even pleats on the squab and on the seat back. The rear seats had 14 pleats across. See images for an example of the original trim pleat style.
  • The vast majority of cars were fitted with black vinyl trim. We have not been able to track down 1965 interior trim colour charts, however, we have been in contact with the 1965 Sports Sedan register administrator who has confirmed several cars were factory fitted with black/white two tone vinyl trim and several cars reportedly had Tan trim. We have also cited cars appearing to have original red trim, and Blue trim. This is purely based on observation so please contact us if you are aware of additional colours and codes, or can provide quality images of examples.
  • Early 1965 cars were fitted with an all-white steering wheel (the same as applied to 1964 model Hamilton built cars). At some stage in 1965, an all-black steering wheel became the standard, which continued into the 1966 series Sports Sedan.
  • Door cards applied to the Sports Sedan had chrome decorative trim routed below/around the window crank, and a buttoned/tufted effect was embossed in the door cards to match the seat trim style. The Studebaker emblem was also embossed into the top of the cards. These cards were introduced in 1964 models, with the style continuing through to 1966 (subject to some modifications).
  • Black carpet and cream roof lining were applied to all 1965 Sports Sedans.
  • Vinyl trunk mat and spare wheel cover were applied as standard.
  • Air-conditioning was optional, and consisted of an under-dash mounted system, which had printed on the front "Air Conditioned by Studebaker". Cars fitted with this system usually also had a sticker on the rear windscreen stating "Air Conditioned by Studebaker".
  • Push-button Studebaker radio.
  • Triple instrument cluster display (instrumentation included speed, rpm, fuel, temperature, oil and Amps).
  • Pop up mirror in glove box, with cup tray built into the lid.
  • The sun-visor clips on the 1965 model are white plastic (as opposed to aluminium, as applied to the 1966 model).

Vinyl roof colors:

Vinyl roof colours were limited to black or white.

4. Chassis Number / Body Tags and original order sheets – 1965 Studebaker Daytona Sports Sedan

Vehicle identification number (VIN):

The Sports Sedans vehicle identification numbers commenced at C510001. It is important to note, however, that VIN numbers of this style were also applied to other 1965 Daytona body styles, as well as 1965 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, if available.

Location of chassis plate / VIN plate:

The VIN plate on 1965 and 1966 cars was spot welded (not riveted) 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-F8" 2-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.

5. Engine Serial Number – 1965 Studebaker Daytona Sports Sedan

The 283CI engine fitted to the Sports Sedan will have a serial number of 805,420,001 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 "80" 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 exist between 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 appear to be absent on the Studebaker engines we have viewed. We have relied on a small sample of engine numbers to make this conclusion, so if readers have any further information, please contact us.

As noted in the preceding section, an original production order sheet will be necessary to confirm that the vehicle retains its original engine. See section 7 of this guide for further details with respect to the 283 McKinnon engines.

6. Engine Block and Cylinder Head Casting Numbers – 1965 Studebaker Daytona Sports Sedan

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.


Cylinder head casting marks and numbers:

Engine cylinder head casting number should be “3795896”. 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.



7. McKinnon 283 V8 rumours – 1965 Studebaker Daytona Sports Sedan:

The 283 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 conrods, 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 specification 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, at some point during 1965 (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 – 1965 Studebaker Daytona Sports Sedan:
  • All Sports Sedans (other than one) were fitted with a 283 cubic inch McKinnon V8 motor (60cc chamber), producing 195hp @ 4800 RPM. One 6-cylinder Sports Sedan was produced using a 194 cubic inch 6-cylinder "Skybolt" engine, producing 120hp.
  • As noted in the engine discussion earlier in this guide, the Studebaker engines have non-embossed valve covers with “Studebaker Thunderbolt V8" stickers on the covers. Rocker covers / valve covers on early 1965 model cars were painted yellow, however, this eventually changed to black for later cars continuing through to the 1966 model (date of changeover is unconfirmed). The engine block and heads were 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.
  • 1965 models were fitted standard with dual circuit brakes.
  • Independant front suspension (coil springs) and live rear axle (leaf springs).
  • 4.5 X 15 inch steel wheels with aluminium hubcaps and P195/75R15 tyres. Firestone Deluxe Champion tires were originally applied with a thin white-wall (See images for an original factory photograph).
  • Prestolite alternators were originally fitted to the McKinnon engines, and alternative fuel pumps were fitted to allow clearance of the cross-member.
  • A single exhaust was standard, and twin exhausts were optional. 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.
  • Twin speed wipers were standard on all models.
