What carb?

It's gonna be Raced, but will be street driven to the local car meets. I did leave out that it has a 4200 rpm conv. Sorry to say I dont know the cam specs. Don't suppose there's an easy way to figure that out? As for tire size, I'm not sure yet either, what size i'll need for the 4.10's without running of motor at the end of the 1/4.
