That would be called a Chevy 307 bored .40 over.
It can cost between $500 and $2000+ to rebuild a 307 Engine on a Chevy Nova. It all depends on who is rebuilding the engine, the brand of the parts, and where the parts are bought.
A 1987 Chevy Caprice Classic with the original engine does have a carb and the engine is a 305, because I have one. This can have a 307. I have an 87 Caprice Estate Wagon, with a 5.0 liter 307 olds. Which, is actually for sale.
Pontiac didn't make a 307. If it's an Olds 307, you need an adapter or a BOP transmission.
1969-1973 chevy 307
Despite being nearly the same size, they are 2 very different engines
There is basically no difference. 305 is a Chevy engine and the 307 is a Cadillac engine. They are both the same and assembled by same company Well, on the other hand, it depends on how you look at it. The 305 Chevy is a 265 stroked with a 350 crank. The 307 Chevy is a 283 stroked with a 327 crank. In theory, the 305 should produce it's best torque at a lower rpm than the 307. However, the 307 should be able to rev higher and produce a higher peak horsepower. Kinda depends on what you need it for. There is also a 307 produced by Oldsmobile that is a V8 engine. It shares no other commonalities with a small block Chevy.
Oldsmobile used to make a 307 V8, but it has nothing in common with a Chevy V8.
Chevy didn't make a 306. A 302, 305, and 307, all of which will work just fine.
chevy did not offer the ss package on 307 cid engine as far as I know they did offer it on the 350 cid how ever
The base engine was a 250 inline 6 cylinder. Also could be ordered with: 292 Inline 6 307 V8 350 V8 396 V8
