Hey everyone, hope your having a great Labor Day weekend! I want some opinions on throttle body size for my 89 5.0, I currently have an E-303 cam with GT-40 heads, Cobra intake and 24# injectors with a 65MM Throttle body, I plan on ditching the GT-40's for the AFR 165's (some real badass heads from what I have read), so my question is what size throttle body should I go with?? Should I stick with my 65mm, go with 70 or even 75MM??? Your opinions are appreciated

THANKS!
