1964 F-85 & Cutlass History
General Motors introduced a new mid-size platform in 1964. Buick, Olds, and Pontiac dropped the sub-compact line of '63 and migrated the names of the Skylark, Cutlass, and Tempest from their compact models to the larger platform. The 64 Olds Cutlass was a trim package based on the baseline F-85 model. F-85's and Cutlasses were offered with a v6, and two v8 engines. The v8 was the new 330 and came in both a low compression 2bbl version and a high compression 4bbl version. This same v8 block would continue production into the late 1980's and see displacements of 330, 350, 403, 307, and 260 (There was even a diesel version of the 260). Three transmissions were available. A 3 speed manual, a 4 speed manual, and a 2 speed automatic. Late in the model year, three months prior to the release of the 65 models, Oldsmobile executives demanded the production of a GTO competitor. Olds marketing assembled the 442 trim package. It was nothing more than a Cutlass with the B-09 Police pursuit package and some 442 badging. the 290hp high compression v8 was fitted with a dual snorkel air cleaner and it's advertised horsepower was increased to 310hp. Also included as standard was a 4 speed, dual exhausts, and a unique rear anti-sway bar (the first US mid-size car to have one!). 2999 442 were produced, most were Cutlass hardtops, some were sedans and convertibles, and a handful were 4 doors. Identifying a 64 442 is simple, determining if it is authentic is very difficult. 442 badges on the fender fenders between the headlights and the wheelwells, and a 442 badge on the rear decklid on the passenger side. Originals had dual snorkel air cleaners ( dual snorkels could be had on Cutlass models as well, despite any recently published 442 restoration guides may lead you to think ). Original 442's had unique boxed lower control arms for the sway bars. All 442's were produced late in the 64 production year, so the date of manufacture should be the summer of 64. The 330cid powerplant used a 3.938" bore and a 3.385" stroke (the same stroke for all Olds smallblocks, 260-403). The cranks were forged, and the valve train used a rocker shaft ( unlike the small blocks of 65 and later which used individual rocker pedastals ). The cam profile on the 4bbl cars was duration: 278/282 lift: .430/.432 (Int./Ex.). The Rochester 4GC 4bbl was used in 1964 (this is the same flange as a squarebore Holley or Carter AFB/AVS). The Standard Cutlass engine was the 290hp 330 V8. F-85's could be had with a 230hp 330 V8 or a 155hp V6 as a standard drivetrain, the 290hp V8 was an option. The 230hp V8 used a 2bbl Rockchester carb and 8.75:1 compression. The 290hp V8 used a 4bbl Rockchester 4GC carb and 10.25:1 compression. The 155hp V6 was a 9.0:1 compression Buick engine and was available in F-85's in 1964 and 1965. It was replaced in 1966 with the "Action-Line Six" which was a Chevy L6. A 3.08:1 rearend was standard on all Jetaway cars except the V6, which came with a 3.23:1, and the 230hp V8 Jetaway which came with a 2.78:1 . A 3.23:1 was standard on all standard transmission car except the 230hp 330 V8's, which was a 3.08:1. Option ratios on all engines were the 3.90:1 and the 3.36:1. The 2.78:1 was an optional economy ratio on 290hp Jetaway cars.
Interchange Info: The rebuilt water pumps are hard to locate but they can still be found (keep calling! and consider keeping your old core). If you switch to the 65 and up water pump, switch the radiator too. Rear axles: 64-65 Cutlass and Buick Skylarks. The axles GM used in these A-bodies were made out of weak steel. the bearing races are made of tougher steel than the axles, so if the sealed bearing fails... the race spins and the axle is useless. then try and find a replacement! You've been warned. Rear axle housing: 64 Olds only. Glass: rear window, side windows, and windshields interchange on all 64-65 GM A-bodies (Cutlass, Skylark, Chevelle, Tempest..). Trunk lids and doors: 64 and 65 Cutlass doors and truck lids interchange. Rear quarters: The outer skin of a 64 will fit the 65, but not the inner fender or wheel wells. The chassis of a 64 Cutlass is not identical to just any 64-67 GM A-body. The front rear suspension is generally the same for 64-65 Buick and Oldsmobiles A-bodies (but not Chevrolet and Pontiac). Some components are 64 Oldsmobile only. The front suspension's draglink (or centerlink) was used on 64 model year and some 65 model year Oldsmobiles and Buicks. There were two draglinks available, a 7/8" dia. draglink and 15/16" dia. draglink. This part is getting hard to come by. McQuay-Harris discontiuned it and it seems that the only place that sells it is Rare Parts, Inc.. Its quite expensive if you purchase it directly from Rare Parts, Inc. (try $275), however they give volume discounts to Autozone, Advance, and other large parts carriers. The draglink can be obtained for less than half of that $275 price that Rare Parts lists. Gas tank: 64-65 F-85 and Buick Special '64-66 except wagons. The ball joints are still widely available and are general in stock items at most parts retailers. The lower control arm (LCA) bushings are somewhat available, although the rear LCA bushing is difficult to track down (Note that each LCA has a front and rear bushing and the two are not the same).
