Thanks for the tips. Sounds like I'm going to have to really pick the brain of the engine builder and get his thought also. He got the shop from his dad and has a long time following from the Pontiac crowd. When I first approached him about the 350HO and explained that I just wanted to refresh it and keep it stock, he commented I could do that, but I would really have to watch my tune. Didn't ask for clarification at the time. I got really excited when I was doing the research and found that I had a 350HO with #48 heads. Factory 325HP with no build, COOL. Now I'm coming to the conclusion that I can't really run that engine on todays gas. Or I can, with a bunch of modifications. Hardened valve seats, Lower comp pistons, different cam. Then its not really a 350 HO then is it? I got all summer to decide..........
