port velocity between LS1 heads and LT1 heads? i want to know if both heads LS1 and LT1 flow the same say 275 cfm, who will have the higher port velocity? the LS1 or the LT1? since i saw a heads/cam LS1 f-body that ran 10.82@125 mph with heads flowing 270-275 cfm where the same heads/cam LT1 f-body will run cosiderably slower with the LT1 heads flowing the same cfm maybe 11.7-11.8@115-117 mph, does that mean the LS1 heads have higher port velocity?

Re: port velocity between LS1 heads and LT1 heads? There is way more to it than that.
Cam, exhaust, induction, tuning, suspension, drivetrain, driver skills etc.
I dunno if there is a way to measure port velocity accurately other than maybe a simulated CFD program.
