Well I don't think this can be done by a farm boy with no money to spend on it. Sell the fuel injected 302 to somebody who needs a f/i 302 and use the money to buy another donor car like Richard did. An older car or pickup with a carb that's been wrecked or rusted but still runs good. It could cost less than buying a good used transmission. And you'll have all the parts you need to complete the swap. If you're really a farm boy you could even use the old body for a chicken coop. That would make streets happy. Nothing wasted. Ford parts cars are usually cheaper than Chevys. I just bought a rusty 80 Firebird a couple of months ago for $300, pulled the Chevy 350/350 and sold the body on ebay for $250. I found a new accel ditributor cap, coil, rotor, ignition module and plug wires in the trunk. Old Firebirds are much cheaper than old Camaros.
