Re: holley stumble?
6" @ idle? are you sure? what kinda cam? HUGE?
cuz I have a hard time w/ 6" vacuum
I'm running 234/244 flat tappet in a 350 and have more than that.
have you messed w/ carb already? if so set back to stock settings.
try 1.5 turns out on idle mixture screws to start, 800rpm idle speed.
if it's not 6", try 6.5 PV's, #28-31 squirters, 65 mains.
blue smoke = oil getting into intake somewhere
got good intake/head seal? I had a squished intake gasket @ 1 port and it wanted to suck in oil.
Also had an intake manifold w/ pinhole casting defect that introduced oil into system
what's the timing? 16-18deg initial?
