At this point in my engine re-build is it necessary to change the throttle body to a larger one..if so whats a good recommendation.......engine now has AFR heads, CC305 cam, and the rest is basically a stock re-build.......or can i re-install stock throttle body and be ok......

 

no reason why the stocker wont work, unless its broke

 

you might gain 5-7rwhp from a larger one, so I guess it's up to you if you think you need it. A bored stocker (out to 52mm) would more than support the flow needs of your engine, and the stock one is probably not going to be a big restriction with that small cam.

 

Guess i'll leave the stock one for now....its not an all out race car...just trying to go a little faster without losing to much drivability....
