I ran the CC .650" 290@.050 sft in my stock 440SP motor, didn't class that as big at all, it ticked over at 900rpm, sweet as, even without the CR it really needed,

Car was 3000lbs race weight, ran a best of 11.2@118 with stock 906 heads.

Added a pair of 2.14/1.81 mildly ported 906's, (probably 255cfm) went 10.7@125 which would've gone 10.5's with more air in slicks, and a few tweeks, was in 1990 and knowledge wasn't what it is today.

So working on that gain from stock 215>220cfm 906's > to BV 255cfm 906's = .5/sec gain, what would it run today with a pair of Trickflow 240's, (328@.650) 10.0's?...the cam/converter/gears/tyres were there for it....just theorizing....would love to get that back and run it today with the 240's to see, and all this from a stock balanced s-pack bottom end, a crappy Team G, small 850DP and just 10:1CR....anyone reckon I could've got into the 10.0's?
