I have it done. I can show you at the meet. Or I guess I could go out and try to get pics today or tommorow.

How much does it help 0?
So pretty much you just sand off the fins. Epoxy the back side of it, and then grind the back opening part to form a cirle? Thats it?

Purty much. Throttle response is WAY better. Gains are within 1hp of the expensive FC unit.

all you need is a dremel and some epoxy... epoxy up the thin edge close to the throttle body spring area and the back of the throttle body... grind away with the dremel to make a smooth transaction from the top of the throttle body to the butterfly of the throttle body.

Yeah, I found a how-to. Looks pretty easy. I'm just waitin for epoxy. I already polished the metal bracket. Chromie is getting more chrome under the hood this summer.... :twisted:

I have done several SVT tb's and I am working on another one right now.

It's not real tough, I would suggest using JB weld rather than a regular epoxy though.

BTW- I am running a stage 2 ported tb from the now defunct SVT salvage, It's soooooo nice.
