I have a Tvr 350i rover v8 on a rover sd1 auto gearbox
If the rover v8 is Buick engine would a Buick v8 fit on to the rover gearbox ?
Silly question but I need to know

Hi
the buick 300 and 350 will as is, though they are not brilliant engines they will match up on the bell housing and the engine mounts will be OK. . . the 400 and 455 series will not match the bolt pattern and the mounts will be different, all of them will be much heavier. Adapter plates are cheep and easy to use but to be honest just dump the rover auto and get the matching auto box for the engine you want to drop in, a rover auto behind a 455 would last about 100 miles before second started slipping! 302 fords have been done in what is basically that chassis. . . by TVR in the original Tuscan, a chevy small block is a bit heavier but offers more power for the same money. Have a think about the ford mod engine, always about the cheapest engine available on ebay.
Back on the 400 or 455 series they are a thin wall casting for a big block so for a big block they are light. . .but that is for a big block, they are big heavy engines, a crank alone is about 80lb weight.
best regards
Mike

The Buick 215 aluminum V8 uses a "dog ear" bellhousing pattern not shared by later 1964-up GM engines, including other Buick V8s. The 1962 and 1963 Buick V6 also used this bellhousing pattern but switched to the 1964-up GM corporate Buick/Olds/Pontiac bellhousing.
This only applies to manual transmissions but be aware the pilot hole in the Buick crank requires a different diameter bushing than the Rover bush and the GM bushing doesn't fit the Rover input shaft. I just bought one of each and took them to a machinist and told him I needed the outer diameter of one and the inner diameter of the other.

The Buick 300, 340 and 350 use the 1964-up GM corporate Buick/Olds/Pontiac bellhousing and will not bolt directly to the Rover gearbox bellhousing.
If you decide to change transmissions, GM had two basic 4 speed (plus lock-up torque converters) automatics: 700R4 and 2004R. The 200R4 is smaller and lighter than the 700R4 and was used behind the turbocharged Buick V6's so should be strong enough, if properly built. After 1964, there were two corporate GM bellhousing BOP (Buick/Olds/Pontiac, also shared by Cadillac) and Chevrolet. D&D in the United States carries the adapters. I think the only thing electronically controlled in the 2004R and 700R4 GM 4 speed automatic overdrive transmissions is the torque converter lock-up and some early models were vacuum control. There are various kits to make the control manual, vacuum and/or electronic. The 200R4 was phased out around 1990. I don't think it ever got an electronic valve body. The 700R4 was also hydraulic valve body and evolved into the 4L60 which became the 4L60-E when it got electronic controls.
