Thread: 327 build opinions

Tweet

I think if the guy knew it was a 302 he would have wanted a lot of money for it. The build looks pretty good to me, AFR heads run good with single pattern cams so you did good on that part. The cam should be alright on a 350, but you actually don't need that big of cam with AFR's. They flow very good and you want to watch how much overlap you put in the cam on smaller engines. If it is a 327 you should find a cam with less overlap. You don't want too much. As for compression, I believe the cam you have recommends 10.5 to 1. You have around 10 to 1? So the smaller 280H might be a better cam for you. 1.6 roller rockers also adds more overlap, so you may want to consider 1.5's.

i see that this is most likley not a 327 with a cast # of 3970010

What is the 2 letter suffix, passenger side, front, just below the head?
Flat stamp plate looking up at you.
