Approximate horsepower

back in october nick's garage dyno'd a 318 stroker, 10.5:1 with the small valve 360/340 heads that had been ported and bigger 2.02 intakes put in (allegedly), comp XE275HL 528 231/237, stock hydro rockers, performer RPM with a 750DP, running thru manifolds

hair over 400hp @ 5500
about 440tq @ 4200

so you've got wayyy more head, roller rockers, better exhaust, but less cam and carb. i think your numbers will be close to that. 385/415
