hey i swaped out a 350 from a 88 blazer 2wd that comes with 210hp factory, i have headers, custom 3inch Y-pipe, 3 inch flowmaster exhaust without a cat, 350 injectors, and bored my tbi unit, also a chip from TBICHIPS.COM, msd cap and rotor, msd street fire coil, open element intake, egr delete, 180 degree thermostate, and new plugs and 8.5 wires. any suggestions or guesses?

You can't hope for any better than 250 hp with those heads and that cam. Those heads won't get you past 300 hp regardless of cam.

yea i figured about 230 if i was lucky
