That Grem is awsome too! 11.5 to 1 comp is alot with todays 10% alcohol junk 93 octain. Barry claims I should have no trouble hitting 600 HP with my mild build. 10.4 to 1 comp,HLR heads( will never recommend them to anyone )  323 cfm @.700 lift @ 28" water on the superflow with 2.1 int and 1.625 exh, small flat tappet 260 dur @ .050,  570 lift cam, HLR intake ported to match the heads, Demon 850 carb, Have other carbs to try as this will be dynoed. Also have a few intakes and headers to test. should be interesting. I am shooting for 500 HP on New englands crapy gas.
