Sweet Anola Gay I am backfireing
New to this site and Kind of new to the hotroddign gig hence I have a question.
I picked up a 1966 BelAir with a 454 in it our of a winnebago and a 650 cfm edelbrock Carburetor, I turned over my fuel and air mixture to 2 and a half turns because this is what I was told was a standard setting for a carburetor and since then it seem that when I put it to the floor I am backfireing from my intake manifold. I also have a leak in my exhaust manifolso my question is which of these problems would you geuss is causing the backfire or if neither sounds right what might yall believe could be the problem
