My setup is very similar to yours.
I have recently upgraded from 62 to 68mm... seems good for me... dyno will measure it on friday.

Professional Products has stock like TB's for an awesome price in those sizes.

Optimum is a relative term. I think with the camshafts youre using, and the plenum volume of the Performer X, a 68 will be enough. Youd probably see a TINY increase in peak HP with a 70mm, but thats just speculation as , as the mantra goes, every build is different.

What size is the H22 throttle body? Is it a bolt on to a b-series intake mani?
