I ran a 10.5 to 1 408 in 3150lb duster. With mild ported eddies and 248/577 roller 3k stall and 4.10s ran 11.20s@118. Put on indybrocks, and ran 2 passes only went 11.09@122 with bad 1.65 60ft. No oiling mods, but 7qt pan. Ran it to 6800 rpm all the time. Also carb I ran was proform 950. Intake was an m1 then a victor. You will be surprises how well it will probably run.
