I have a 307v8 and would like to put a four barrel carb on a free edelbrock manifold that I got from a friend.

When I went to Autozone, the "kid" was trying to sell me carbs that were 800 cfm to 1250 cfm, this seemed like way to much carb for a stock 307. When I told him this, he said it was related to horsepower. The shocking part was that the manager was also intent on selling me one of these carbs also.

I shook their hands and walked out the door. I was hoping that they had not been drinking or something worse.

I know that there is some math formula for figuring out 4-barrel cfm, but I forgot it.

Thanx
Dano
