Throttle Body Size?
My current combo is a 347ci with a S-Trim pushing 10-14 lbs of boost depending on conditions, 42lb injectors and a Comp blower cam, FPS 200cc runner lenght heads, Edel RPM Performer intake. The car put down 510rwhp and 510rwtq. I currently have a 65mm TB on the car, but have been wondering if a larger 70mm or 75mm TB would give any increase in performance, any input is appreciated, Lee

anyone have some input on this? about to build same combo, would like to know which t.b. and egr size to start with.

I called Accufab,, George recommended a 75mm TB.... I spent my money on a sumped tank, Eaton 31 spline diff and Strange Axles,,, so the new TB is out for now... Lee

Not sure if it will really make much difference.....
I have ran 24 psi through a 75mm TB if this helps.....I would imagine a larger one would benefit me but how much HP??? probably not much!
So if you have the money a bigger one would be in order but not necassary I'd say!
