the question is who has the most hp 383 block, especially na, but adders is cool to.
383 block only?
probably some guy with a stroker pushing close to 500 cubic inches and nearly 800 hp.
unless someone has a hard fill, main girdle, etc.
if I was going to build a stock stroke 383, it would be an RPM motor with big heads, light rods and pistons, and I'd spin it 7500 or 8000, or however much RPM I could get stable valve train out of.
but for a fun street driver, I think the stroker I put into my 383 is just about perfect! 505 hp, 535 torque flywheel numbers, with a broad flat torque "curve" only thing I'd do different, is some port work on the Eddy heads and maybe a tad more cam and RPM to eek out closer to 550-600 hp. right now it maxes out right at 6,000 rpm.
