Funny thing is, I never messed with it, cause I didn't have to. He dialed it in on a roller 408 Ford, I put it on a roller 406 Chevy, and never even pulled the bowls off. Whatever the jetting was, it ran great. (I didn't find out how "big" it was, or what jet, till I rebuilt it cause it sat for a few years. It had the next to the biggest sleeves I had for it, the blue ones)
