Hi all: I am a little confused and could use some advice. I just purchased a 390 engine from a 74 ford pickup. It is without intake manifold. I am seeing some on ebay, but all give year ranges that they will work on. Many yr. Ranges stop at 1970. Will these work for the 1974 engine? I am transplanting this engine into 1967 mustang coupe. I know i have to change headers to work in car since engine came from pickup truck. Any other info or advice would be appreciated. Parts are expensive and i don't want to buy the wrong parts. Thanks a lot. --max--
