Holley 750 4150 82751 I bought this carb used and I think the jetting is all messed up. I want to put it back to stock for a starting point. I've sent holley emails but I never hear back. I've searched google and the best jetting chart I found has every carb except mine! I have 70-78 jets in it...
ok here is the rundown, just bought the car and am trying to tune it . this is what i have been told and what i can verify so far.
victor jr intake
1.7 roller rockers
full msd ignition (dist,6al,blaster 2 coil)
holley 750 dp carb (4779)...
