That's a lot of work, fantastic you are building some fast wheels. What 302 are you working with? It always bothered me that it is a 4.9. Other than our Ford truck 4.6, our hot rod is a 6.1 Challenger 425hp natural. It is going to get a boost, Demon type hype so we hope. The money is considerable & nothing is easy, but we boost where we can. Tires first.
