So the title may be a bit more flashy than the actual situation. I have a 69 Chevy truck that previously had (i think original) a 307, which i pulled. It now has a 305 out of a Camaro. I'm working on an ever decreasing budget, so a crate motor wasn't in the cards. My dilemma is that I am not upgrading much more than the intake, carb, and clutch (not really an upgrade but more so a newer clutch for the motor to mate with the 69 3 spd trans). The headers off the 69 307 fit the 305 heads decently, no clearance issues other than only being able to thread 5 of 6 bolts on passenger side of motor. Needless to say, this is my first engine swap and I'm finding myself undereducated and in need of some advice. Any help will be greatly appreciated!
