1965 Corvette
For its third season, the 1965 Corvette Sting Ray was not only further cleaned up style-wise, but was muscled up in a big way with the addition of an all-new braking system and beefier powerplants.
A trio of functional air vents in the front fenders, a smoothed-out hood,
and more legible instruments distinguished the 1965 Corvette.
The big news for 1965 was underneath the fiberglass exterior, however. The first welcome addition was the advent of standard four-wheel disc brakes. The brakes had a four-piston design with two-piece calipers and cooling fins for the rotors. Pads were in constant contact with the rotors, but the resulting drag was negligible and didn't affect fuel economy. Further, the light touching kept the rotors clean and didn't diminish pad life, which was, in fact, quite high: a projected 57,000 miles for the front brakes and about twice that distance for the rear binders. Total swept area for the new system was 461 square inches, a notable advance on the 328 square inches of the previous all-drum system. Per pending federal regulation, there was also a dual master cylinder with separate fluid reservoirs for the front and rear lines.
Road testers rightly applauded the all-disc brakes. Testers found that repeated stops from 100 mph produced no deterioration in braking efficiency, and even the most sudden stops were rock-stable. The old drum brakes remained available, however, as a $64.50 credit option, but only 316 of the 23,562 Corvettes built that year came with them.
Another mechanical addition came at midyear, with a new optional V-8. Officially called Mark IV but marketed as the Turbo Jet, the new engine arrived in three varieties: two 396-cid versions, and a 427 (a heavy-duty 427 was also created for marine use). The 396s were scheduled to replace Chevy's hallowed 409 in all its applications for 1965. Future demand for performance cars suggested that Chevy's Tonawanda, New York, engine plant would have to be retooled, and Semon E. "Bunkie" Knudsen, then division general manager, decided that only the most modern engine could justify such a major investment. Mark IV production commenced in mid-1965.
Like the head, the Mark IV block was also new, with 4.84 inches between bore centers, a bore of 4.094 inches, and a stroke of 3.75 inches. The 409 had a deck angled at 33 degrees to allow for wedge-shaped combustion chambers with flat head faces. By contrast, the Mark IV had the usual flat deck sitting perpendicular to the cylinder axis. Main bearings were 2.75 inches in diameter, a quarter-inch larger than those of the 409. Main-bearing width was also increased, adding two full inches to the cap-clamping surface. The forged-steel crankshaft was cross-drilled to deliver oil to the rod bearings through a full 360 degrees of rotation (a feature lacking in the 409). Crankpin journals were kept at a 2.20-inch diameter.
With hydraulic lifters, a four-barrel carburetor, and 10.25:1 compression, the 396 Mark IV offered in intermediate Chevelles and full-size Chevys arrived in two states of tune: 325 and 360 bhp. For the Corvette, the engine was given 11:1 compression, impact-extruded alloy pistons with chrome rings, solid lifters, and a bigger carburetor, all helping to produce 425 bhp. Also on hand were a double-snorkel air cleaner and an oversized oil sump.
Although in short supply at the showrooms, the top Mark IV Corvette wasn't short on performance. Pulling even the moderate 3.70:1 rear axle, it could do standing quarter-miles of around 14 seconds at terminal speeds of 102-104 mph. Given enough road, it would show a top speed of nearly 140 mph. Numerically higher or lower axle ratios would respectively deliver even faster acceleration or higher top speeds (an insane 160 mph was not inconceivable).
The 1965 Corvette marked the advent of standard four-wheel disc brakes.
GM management had initially decreed that no car line smaller than full-size should carry an engine larger than 400 cubic inches. Since the 396 squeaked in under that limit, it replaced the fuel-injected small-block V-8. But with Carroll Shelby installing Ford's impressive 427 V-8 in his sparse two-seater Cobras, Chevrolet felt it would likewise need a 427. It materialized for 1966 -- basically a 396 with a larger 4.25-inch bore.
