i am putting a 350 crate into my 83 camaro, it has the cross fire injection, so this is where i run into a problem, i don't want to have to change the fuel pump if i don't have to is there a FI sytem that is fairly cheap and runs about the same psi in the lines or a carb or am i just gonna have to change the fuel pump, or just use the cross fire injection on the new motor?
