qustion for the mechanics - BooBoo - 06-15-17
I got a 67 coronet with a 383 auto. and a small performance cam , don't know the specs . seems to run good but it leaves a puff of black smoke when I leave a traffic light . I,ll find out tomorrow what size jets and squirters it has in it . its a new holley 750 . but in the mean time could you tell me what setup makes your car run the best ? thanks . booboo

I don't think you are far off as far as jets. My 750 double pumper has 70/80 and 31 squirters. With the O2 gage it was spot on with the 440.
What is in there for a power valve? What size and is it good?

Also a possibility on the idle you could be running rich mine was stumbling slightly off of idel hooked up a wideband and found out I was pig fat on the ldle i'm also running a Holley 750
my idle screws were out like 3 1/2 turns if I remember correctly I think I'm out maybe a turn or turn and a half now.
