Ok so after all the help with the 327, I finally did a compression check and my reading are all over the place. Lets just say I need a rebuild. Well I went over to my fathers house and I had a 283 that I built back 25 years ago. I never put it back together. Its a 66-67 283 block. I had the block zero decked and the internals balanced. I have flat top pistons and a 3863151 cam(327/350hp cam). Everything is there and never been run. I think Im going to put it together. I have read that that may not be the best cam.....so what do I need to look at? I also need to get some heads. Do not know if I want 64cc or 72cc heads. Looking for input.
