Better heads

hi, from all the big flow numbers shown here, what test pressure they taken at? was that 7'38 in the 1/4 mile? or 1/8 mile? just curious. big numbers sell.

perfacar,
It was in the 1/8 mi.. The test pressure is 28".
What some think is that this engine is all tricked out, this couldn't be farther from the truth, as this engine has all stock parts, except for replacment pistons and a M-1 intake and holley carb and a cam from Comp cams, I did go to shorty hedders though.
