So if thats not big what is your definition of big?
Some of you guys should have raced with us in the 70's and 80's and you would get a better understanding of how you have to work with JUNK or within the rules. my Duster ran 9.82 back then at 2950 weight with a .030 over 440 block, 906 heads, stock crank, stock rods, TRW heavy weight pistons, and super stock springs. To get there I used a tunnel ram with two 750 holleys and a 750 lift cam. So with today's way better chassis, tires, HEADS, intakes, cams, and pistons it would be a "cakewalk". A 650 lift cam is not big.
....exactly. We had about 6 Koffel iron 451's over here in cars at £5000 a pop in the 80's, they had max ported heads, ultra thin rings and .750 roller cams, they managed 10.0's in most of the cars that were lucky enough to afford to run them. The MP .590 with
271@.050 is a good cam but its done in most race 440's at around 6500ish with Good modern heads, if you wanna run in the 9's@3000lbs+ you gotta turn one more than that unless your light.
My junk 440 with junk 906's was still pulling like crazy at 6700 in the traps with 290@.050
