stock holley 750 82751 jetting?
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 now and its on a 400rwhp 351w thorugh a c4 and it seems lean but I dont have a airfuel gauge I just know its not running like it should be.
