My question is what everyone else is asking and thats why the open chamber heads ? Do you know the real comp ratio ? And you wont have good quench either. I dont know the specs of that cam off the top of my head but the rest of the combo is not to far from mine. But I use EZ heads and have 10.6 comp with quench and mine runs fine on 92 pump. I use more gear with 4.30's and a 30" tall tire and I may gear down as I dont think it needs that much to run the same et. I run a 9.5 Dynamic street/strip type converter that flashes about 4200 and works good at the track but drives around like a normal converter. I also run a dual plane intake but I use the Indy dual plane which has pretty good size ports and runners and I run a 850 Holley DP. I agree with others that mine may go faster with more carb but it dont run to bad with the 850 and has great street manners with it. But you need to know what your real comp is to start with ? Ron
