425ci

The 425 in³ (7.0 L) big-block was the first tall-deck, "big block" produced from 1965 through 1967. It is arguably the best engine Olds made in the musclecar era, although it never made it into a "musclecar". It used a 4.126 in (104.8 mm) bore and 3.975 in (101 mm) stroke. Most 425s were painted red. All 425 engines had forged steel crankshafts with harmonic balancers.

Super Rocket

The standard 1965-1967 425 in³ (7.0 L) was called the Super Rocket, and was the most powerful engine option for the Oldsmobile 88 & 98 of 1965 through 1967. Compression ratios of 9 to 1 @ 310 hp (231 kW). or 10.25 to 1 @ 360 hp (268 kW). were available in the U.S.

Starfire

A special 1965-1967 425 in³ (7.0 L) V8 was the Starfire engine. The main distinguishing features of this engine were a slightly different camshaft profile from the standard ultra high compression engine and factory dual exhaust. This engine was only available in the Oldsmobile Starfire. It shared the same compression ratio of the Toronado Rocket at 10.5 to 1. It also used the .921 in lifter bore size of the Toronado Rocket.

Toronado Rocket

Another 1967 425 in³ (7.0 L) was the Ultra High Compression Toronado Rocket. Unlike all other 425s, this version was painted slate blue metallic. The Toronado 425 engines had the same .921 in (23.4 mm) diameter lifters of the first-generation Oldsmobile engines rather than the standard .842 in (21.4 mm). This let the engineers increase the ramp speed of the camshaft for more power, 385 hp (287 kW), without sacrificing idle or reliability.




































A new version of the V-8 engine was offered for the 1965 model year, this one measuring 425 cubic inches in displacement, still using a Rochester 4-barrel carburetor and generating 375 horsepower (280 kW) at 4800 rpm. This was still the most powerful engine in the Oldsmobile lineup and used only in the Starfire and the Jetstar I. 1965 sales were 13,024 for the coupe and 2,236 for the convertible.
