400 to 451 stroker questions

Back in 1991 my 440-6 stock balanced bottom end motor (5/16ths rings!, 9.5:1cr) with BV 906's made approx 520fwhp according to weight/mph and 660fwhp with a 175hp (rich jetted for then) shot of N20, single 850DP, Team G dom with spacer for 850 and the juice cam was the Comp Cams .650/.650" [email protected] sft cam....just some more Facts.

My 451 made very similar power on motor and spraying it. Smaller cam, more carb and a better (I assume) n20 tune up. Pretty cool to see the numbers somewhat align 30 years apart.
