ОглавлениеThe new 1965 grille was a smash, as proved by the sales figures. It was obvious that Pontiac had a winner, especially in the convertible.
The following production figures were taken from GM production reports.
All standard 335-hp engines were outfitted with a new, pancake-style air cleaner.
1965 Vehicle Identification Number
The vehicle identification number (VIN) was riveted on an aluminum plate and attached to the driver-side front door-hinge post. There was also a date stamp on the VIN tag indicating date of delivery to the original owner. For 1965, the example of 237275P100001 decodes to:
| 2 | Pontiac Division |
| 37 | LeMans |
| 27 | Two-door coupe (37 for two-door hardtop, 67 for two-door convertible) |
| 5 | Last digit of model year (5 is 1965) |
| P | Assembly plant (P for Pontiac, B for Baltimore, K for Kansas City, Z for Freemont) |
| 100001 | Consecutive sequence number |
Because the 1965 GTO was an option on the Pontiac LeMans Series, no specific number or code indicated a GTO. When production reached 100,000 at a particular plant, the consecutive sequence number continued with 200001. The consecutive sequence number was different for a GTO built at another plant. Also, as the VIN does not show a code for the original engine, it makes counterfeiting a GTO easier. General Motors did not include a code for the engine until 1972 in the VIN, whereas Ford did from 1950 on and Chrysler did from 1966 on.
Starting in 1965, Pontiac revised the block numbering system, using a two-letter code. Above this code is the engine unit number, which is either six or seven digits. This number is not related to the vehicle’s VIN. The block’s unit number is the sequential production number for the engine.
The block codes are two letters and as a general rule, W-code blocks are for manual transmission vehicles and Y-code blocks are for automatics. Most Z-code blocks are also automatics, and X-code blocks can be either manual or automatic transmission vehicles. A typical block code is WT.
The engine unit number and the engine code are located on the passenger’s side of the block, just below the cylinder head.
The date code is also important. It is cast in the distributor pad and consists of three or four characters as follows: The first is a letter representing the month (A for January, B for February, C for March, D for April, E for May, F for June, G for July, H for August, I for September, J for October, K for November, L for December, M for December 1966 [1967 model only]). The second or third is a digit representing the day of the month. The last is a digit representing the year. N or D represents the work shift when the block was cast, Night or Day. (Beginning in 1969, an additional two numbers represent the year; for example, 69 for 1969.)
Cylinder Head Casting Numbers
The cylinder head codes were cast into the center exhaust port area. For 1965, a portion of the head part number was also cast on the left- and right-end ports.
| Cylinder Head | Casting Number |
| 389-ci all | 77 |
Carburetors
The part number for the 1965 Carter AFB 4-barrel carburetor was found on a metal tag mounted on the carburetor air horn. For the Tri-Power carbs, the numbers were stamped on a plate and mounted on one of the carburetor mounting screws.
The 4-speed manual Tri-Power setup received a mechanical linkage that actuated the two end carbs; automatic cars were vacuum equipped. This car has a dealer-installed Ram-Air setup. (Thomas Short Photo)
Distributors
The 1965 distributors had the part number stamped and mounted around the distributor shaft.
Intake Manifolds
On 4-barrel engines, the part number is stamped or cast into an intake runner. On Tri-Power manifolds, it can be found on the center and rear intake runners.
| Engine | Part Number |
| 4-barrel | 9778816 |
| 3×2-barrel | 9778818 |
Exhaust Manifolds
The part number for the exhaust manifolds is generally, but not always, found on the outer face of the manifold.
| Location | Part Number |
| Driver’s side | 9779032 |
| Passenger’s side | 9779325 |
The transmission codes are:
On the Super Turbine 300 2-speed automatic, the transmission code was stamped on the low-servo cover on the passenger’s side of the transmission or on a metal tag.
The 3- and 4-speed M20 and M21 manual transmissions were used on the GTO and, generally, but not always, had the part number stenciled on the transmission case on the driver’s side of the case, at the rear of the cover. The code number indicated the type of transmission and the production date.
An identification code is marked in yellow paint on top of the case on 4-speed transmissions: W stands for wide-ratio and 9 stands for close-ratio. On the 3-speed Tempest (Muncie), the letter X indicates a heavy-duty Muncie and is marked on the passenger’s side of the case. The letter S identifies a midyear (March 1) introduction of the 3-speed manual Dearborn transmission.
1965 Rear Axle Identification, Codes and Ratios
In 1965, differential codes were stamped on the back passenger-side axle tube. The codes identify which axle ratio was used and if the axle was equipped with Safe-T-Track.
The GTO has the following items as standard and were not available on other LeMans models: the vinyl-trimmed assist bar over the glove box door, a GTO emblem located to the left of the assist bar, and a GTO emblem mounted on each door.
Exterior color codes can be found on the cowl data plate located on the driver’s side of the firewall.
The hardtop and coupe were also very stylish, especially with the Cordova vinyl roof. Note the 6.5 emblem on the front fender, while the GTO was placed on the rear fender.

Option Groups
Compiling multiple options into a single option group was a way of creating less confusion and paperwork for dealers.
The 1965 Convertible had a more up-to-date front grille, which was a precursor to the 1966–1967 GTO. Compared to the simulated scoops used on the 1964 GTO, the 1965 hood scoop looks functional.
Is My Pontiac LeMans a True GTO?
The GTO option was listed as an option on the LeMans Series for 1965 and not a separate, freestanding model. In addition, the engine can easily be substituted by another engine because there is no code for the engine in the VIN. On the other hand, an original GTO must include the hood scoop, front fender GTO crests, rear fender GTO emblems, and a rear deck GTO emblem. The interior includes a vinyl-trimmed assist bar over the glove box door, different GTO emblem located to the left of the assist bar door, and mounted GTO crests on each door.
The GTO received its first restyle in 1965. The GTO was still an option package on the two-door coupe, hardtop, and convertible LeMans.
Exterior
The front end of the car had a totally new look with vertical headlights and a split, recessed grille. The new front end was deemed to be more modern and fresher than the 1964. The hood had a simulated single hood scoop; however, the scoop became functional later in the model year with a dealer-installed Ram-Air system.
The GTO emblem was placed on the passenger-side rear of the deck.
On the rear, the most noticeable changes were the wraparound taillights and the fuel-filler door location, which was moved behind the license plate. Large “PONTIAC” lettering was now placed outward on the chrome ribs. The identifying GTO emblems were again located on the driver-side front grille, rear quarter panels, and on the deck lid, as was the 6.5-liter crest, which remained unchanged on the front fenders. A total of 15 exterior color choices were still available with 2 Cordova vinyl roof colors and 5 convertible colors.
The trunk on all 1965 GTOs was painted spatter blue with green/gray flecks, in contrast to the 1964 trunks, which were painted body color.
Interior
The interior on the 1965 GTO was marginally revised. Instead of the engine-turned dash appliqué used in 1964, a wood veneer was used, which can be either vinyl or real wood. Although the dash pad is similar to the 1964, the grain on it is different from 1964. Other differences include the addition of a vinyl-trimmed grab bar over the glove box door and a GTO emblem located to the left of the grab bar. Two small GTO liter crests were mounted on each door panel.
The four-pod instrument cluster remained the same; a new Rally Gauge Cluster was now optional, which used different instruments for 1965. On the far-left instrument pod, a fuel gauge was located on the top pod, and a battery indicator was located on the bottom pod. On the left-center pod was the 120-mph speedometer and odometer, along with an optional parking brake indicator light located beneath the odometer. An unfurled checkered flag was located just above the center of the speedometer.
The four-pod instrument cluster remained unchanged; however, a new Rally Gauge Cluster was an option with different instruments.
Next, on the right-center pod is an 8,000-rpm tachometer of which two types were made. The early cars came with a green band that sweeps from 0 to 8,000; on later cars the green turned to red from 5,200 to 8,000 rpm.
Finally, the far-right pod contains a 0–230-degree water temperature gauge on the top, and a 0-30-60–pound oil pressure gauge on the bottom.
The Rally Clock was optional with the standard instrument cluster. The 1965 heater control panel was redesigned with the addition of a moveable vent located above it. The standard steering wheel was again the LeMans Deluxe wheel and came with a round horn ring. The optional three-spoke Custom Sport steering wheel featured a deep, three-spoke design.
A new radio was made available, a mono AM/FM unit, with either the standard manual or the optional electric antenna. The power antenna was relocated to the passenger-side rear panel, and the manual antenna remained at the passenger-side front fender.
Under the dash, a hazard warning light with a red light pull switch was located on the left of the steering column. The consoles for either manual or automatic transmission were a carryover from 1964 with one change: The area between the ribs was painted black. It was blue in 1964.
Finally, seat upholstery was changed to a diagonal rib pattern design.
Chrome exhaust splitters were used on the GTO. It was a nice touch.
Engine and Transmission
The standard engine on the GTO was the 389-ci V-8 rated at 335 hp at 5,000 rpm. Compression ratio was 10.75:1. Carter carburetion was used on the engine. The lower end of the engine used 3.00-inch mains and 6.625-inch long rods. The optional engine was rated at 360 hp at 5,200 rpm and used the Tri-Power induction system. It consisted of three 2-barrel Rochester carburetors, and the end carburetors were mechanically controlled, giving the GTO more power at a lower engine speed.
As before, all Pontiac engines used an oil windage tray and were equipped with chrome valve covers and a chrome oil filler cap.
The standard transmission was a 3-speed manual with a Hurst floor shifter. Optional were two 4-speeds: M20 wide-ratio box and M21 close-ratio box. All manual transmission cars came with a 10.4-inch-diameter clutch.
The 2-speed Super Turbine 300 Powerglide automatic was optional on both engines. It was not until 1967 that the 3-speed Turbo-Hydramatic became available.
All GTOs came with a dual-exhaust system. The head pipes measured 2.25×0.075 inches, and the tailpipes measured 2.00×0.049 inches. The head pipes on the Tri-Power engines with manual transmission measured 2.25x.055.
