Alright, if been looking which direction i should go with my buildup and I'm going bugget oriented. GT40 heads i have seen come in different variations. Ive seen gt40 x y and p I think? I also know some came on the 5.0 explorers, which ones. What heads will the kenne bell accept, and can u bolt the KB for the 302 on the 351 with the lower intake manifold conversion. Also, i may get my hands on an early 70's 351w block with 200,000 miles on it. Is this block maybe seasoned a Little to much :noes: ? What do u all think. Last question i promise... for awhile.... I'm going to wyotech and taking performance engine buildup and hand porting. How well do u think u could get the gt-40 whatever heads flowing with a good 3-5 angle valve job and port matching it all. Maybe as good as the AFR or edelbrock equivalent?
