no I respectfully disagree. I am running 305 Chevy TBI heads on my 1971 Chevy 307 and all is very well.
307 pistons are 3.875" diameter. 305 pistons are 3.736". It might be possible to bore a 305 large enough to accept the 307 pistons, but the wrist pin location would be .230" off because of the different stroke. In short, no.
Yes you can.
no comes stock with a 305
yes
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.
Yes, I've got a 307 running 305 heads in my old truck. I read somewhere it's actually worth a few extra horsepower
Oldsmobile used to make a 307 V8, but it has nothing in common with a Chevy V8.
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.
Yes they will, but 305 heads have a smaller combustion chamber so it may raise your compression ratio.
Oldsmobile used 307s in those days, not 305s - the 307 had 140 hp
How can you tell a 350 from a 305 engine?
