CFM choice
I built a 351w for my show truck and am not sure what cfm carb to use. the engine consist of bored 30 w/flattops, 496/500 lift comp cam, ported stock heads w/trickflow spring upgrade, ported and polished performer intake, bbk headers and the usual other upgrades. I have a 600cfm holley and would like to know if it will carry it. I've already sunk a ton of money in it already and would like to get out as cheap as possible on this. thanks

It'll work...by show truck I am guessing your not after peak hp and tq, so the 600 should do fine...nothing extreme about your combo. You should stick some pictures in your gallery. What year truck you working on? Whats your idle rpm and does it have any lope, thats a XE262 right? Later
