true. yea cams 280/280 at 50 and 520/520 lift on 110, maybe the 282s cam better, wee bit more duration and probly 40 thou more lift. yea thats why i was wondering about carb bein too small, not feeding it up top which could be the problem, still have the stock fuel pump and 3/8" fuel line which i should probably sort so its got more gettn to the carb when it needs it. not sure about dissy curve havnt had that seen to yet and still learning about that aspect, was on a strip 350 before i got it though if that would make a difference, timing is 8 btdc, yes vacuum advance, manifold edelbrock performer rpm, and yea about heads, thats them haha i have stock 3993820s from the 402 but couldnt have had the work done to them that these others have for the price i paid for them
