im sure you guys have gone over a million times but im trying to get my car running at its best so any help=THANKS!
ok heres the problem, got a 650cfm double pumper w/stock jets had it for years=old carb, i had a problem with the carb making whistle under slow speed, but the went a way=(not sure how or why if it got worse, or what) i thought for years my 289 was over carb'ed but i just put a 331 scat stroker kit w/flat top, with some world sr heads, rpm air gap intake and a 512/512 292 the car idles around 7hg in park and around 5hg in drive, seems low to me, cause the 289 used to be around 10hg if i remember. also keeps spitting out the carb if you give to much pedal before its under 190temp, the car seems that it got more stumble under 2k then flattens out about 5600rpm sounds crazy but no moving that much at that rpm. i tried a 670 street avenger with the 289 before i sold it case it didnt semm to have power in the upper end(wish i still had it to try now) but im looking at buying a carb, my cuz says to put a 750cfm on there but i think it might make it stumble more.
any help?
been looking at the new holley 0-76750BK
