I think where Jeremiah was going was there'd be measurable gains just hogging the 240's open to MW area and using a MW intake. This too would make your 'small' cam seem bigger.
I wonder if the 240's have enough metal in the right places to equal Indy SRs? A guy i know, and pitted next to, had a 499 with heavily ported SRs, ran an 8.37 at 2500 lbs with them.
