This is 305:

And this is 307:

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.
no I respectfully disagree. I am running 305 Chevy TBI heads on my 1971 Chevy 307 and all is very well.
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?
