Yeah, check out the difference it made with Rubbles car. You won't get big hp gains from the throttle body until it becomes the restriction.I'm sure the addition of heads and cam will necessitate the need for the KB. Consider it a piece of an upcoming mod instead of an expensive paperweight. Glass half full thing you know.....
I just kept the stock one on for the moment, seems to work pretty well with the KB on a stock bottom end.I been looking at TB's myself. 90 or the 100. I still have not decided.
What size did you end up getting?
