Are there any companies that do overbores on the stock 99+ 4.6 throttle body?

I know the TB is a pretty big restriction on the 03-04 Cobras because of noise pollution laws Ford had to follow, are these any bigger than the GTs or would they be roughly the same?

thanks jd for answering me. heh

Yeap... its called Drimmel! You go out and buy a Drimmel and bore that puppy till its thin as paper and throw it back on. Why pay someone when its that easy???

i already have a dremmel but I'm not going to do that myself.

Should only be like 20-30 bucks to have it bored out, but i might as well get it polished while it's out.

basically what you're saying is you don't know of any company that does this for you. thanks.

See, I did that with the dremmel, and I've found that things just dont come out flat, you get too many waves and surface variations, so i figured in the end, I'd probably do more bad then good and jus settled for polishing.

You could bore it out, but i dont see much performance increase from it...

Yea but its free and it will flow better than stock unless you mess it all up somehow

I have a buddy that just did his GT40 intake and it looks professional so Im gonna trade my 3.27's for a good port and polish job on my intake.
