I have a 1969 Camaro with a stock 350 and a TH350 trans. It has seen better days, and I am thinking of buying a crate 350 to swap it out with. Eventually I would send it off to a machine shop to have it rebuilt and cleaned up, but that is a ways off. I see lots of options for crate motors on JEGs and Summit Racing, but they indicate they are replacements for particular model years. My question is whether I can buy any 350 crate motor and drop it in the Camaro or is there enough differences between model years that I would have problems? I would hate to spend a lot of money on a new motor only to find that it won't fit in the car.
