"I have a set of W9's on my other R3 block (468 cid) with 59 deg lifter angle. That set of heads is a set of Chapman done heads and they are to small for that motor it gives up at 6800 but it pulls hard in the mid range.
This one is going to get the W9RP that Curtis Boggs from RFD did."

Curious, what kinda flow numbers does a Chapman W9RP have to choke off a 468ci at 6800? work


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
