Chevrolet 307 Engine?
Never heard of it and was curious. Found a good ad on a Camaro and saw it had a 307, so are they worth keeping in or should I replace it with a 305 or 350?

Re: Chevrolet 307 Engine?
The olds 307 is a completely different motor entirely. Strong design(SBO), but weak power. If I was given the choice between a 305 or a 307, I would choose the 307 in a heartbeat. the larger bore and smaller stroke make it a better engine (IMO). I have heard that all 307's wear faster though, due to the lack of nickel in the block. Rebuilds can come as early as 70k.
Cheers!!

I woudln't bother replacing a 307 with a 305.. doesn't really make any sense.. if you were going to replace it put something with some ***** in there.. it may in fact be a 305 though.. notice the "iroc" rims..
