Iam looking at buying a wilson tb for my new motor, I read a thread about this and a few guys said buy the biggest you can afford. That would be a 4500 style wilson that flows 2000cfm. Is that to much? I see smokn ta has a 4500 style and it seems to work pretty well for him. My combo is a iron block 408, AFR 225s, diamond nitrous pistons 13.5-1, custom solid roller nitrous cam26x/27x, super victor efi intake and a bigshot plate.

Accufab has one that flows 2128cfm...

You will have to run a 4150/4500 adapter and do some minor porting and matching to get the most out of it,

You don't need all that cfm a 1500 would work fine

Yes this is true, edelbrock does not make a 4500 style super vic. My question is what cfm will work best on my combo.

it's not like old carburated setups, you cannot over throttle a Fuel Injected car If it's all out race use the largest throttle body you can

Well I just had a long conversation with the guys at wilson manifolds, and they said that yes you can over throttle body an engine. He also told me that the correct cfm for my car would be 1388. So 1388cfm it is.
