Jack, have you or anyone else tried the proform carb bodies. I put one on my 71 and now it dumps too much fuel. its poping inside the mufflers when you get on it hard and the back off. I put the jets they sent in. They were 86 for back and 72 for fronts. stock in the 650 holley are 78 back and 67 fronts. its a 71 engine with quinch heads and flat top pistons. the cam is a crowler with more lift than stock.(dont remember specs). I put a duraspark dist. with light springs in it. I tried changing the back jets with the stock but it still does it. I am going to change the fronts as well because it didnt do it before, the timing is set at 10 before.please any help from anyone would be great........ Paul.. I will try anything.
