I was considering picking one of these up, to help make my car look more stock under the hood...but was concerned about the quality of it...they're sold on ebay all the time. This way I have an extra 50 CFM I can use if I rev to 6500, or up to 6250 if I ever choose to stroke to 383. I was wondering about the quality and performance of these throttlebodies. Here's the link:

Naturally I'd get a bolt-in airfoil and run that along with it instead of my cheap clip on one. Anyone?

 

Is it a stock one bored to 54mm. I have a stock on modified to 52mm and I can't see it going any bigger.

A 52mm throttle body flows 750CFM which is plenty big enough for most engines. There's one board member with a head/cam set up running 11.80s with a stock throttle body.
