Its an 85 307 from a 442, Is it do-able? I have a vacuum advance distributor now but i cant get it to run right. The engine should be fine. The block in in great shape and the heads were just remanufactured so im sure it a timing issue. Thinkin maybe the problem is with the distributor? I barrowed it from my 72 olds 350. Just curious if it would work with non CCC carb.
