    the best I did with race heads & roller cam in a street engine was about 440 rwhp from 440 ci so figure 1 / ci
     Best combo for a 340
     R3 Block W8 or W9 heads I heard of a small block stroker build that put a tube chassis car within a few hundreths of Pro stock times in a 400 lb lighter car about 10 years ago so what 800 HP or so  :scared:

    My engine builder did a 360 ci build for Car Craft http://www.carcraft.com/techarticles/ccrp_1110_pump_gas_small_block_mopar/ that put out 620 hp.

    As for the max, I have heard of people getting over 800 hp on pump gas......just not sure how long they lived though.

    The engine is actually 408 cid, but it's based on a 360 block.
