I have a built 302 motor with b303 cam, edlebrock air gap intake, forged pistons and rods. Im trying to figure out what size carb and brand carb to go with? Is holley better or edlebrock? and should i go with 650 or 750?

What heads?

I like Quick Fuels, can't beat the options for the money.

It almost sounds like my set up. I have the Edlebrock performer set up from Summit on my 302. Pefermor RPM heads. I run a street avenger 670 for my carb. There is some crazy formula around on these forums that will size a recommended carb.

I would go with a Holley. I think Edelbrock carbs are junk. So do a lot of the Northeast gears heads. I would alos go with the 650 cfm. The 750 is to big. I had a 750 and top end was great,but I wanted more 1/4 mile performance and more throttle response and I got that when I went to the 650.
