If so what is the cost and contact info?

I have an 01' GMC so my TB is cable driven and not the drive-by-wire thing the new trucks have.
The Nick Williams 90mm TB is 3/4 bolt meaning you can bolt it up to a 4bolt manifold or a 3-bolt standard if you elongate the bottom holes some. Then you just have to port teh J-Tube.
The other idea I had was the Starr 94mm TB bolts up to all standard GenIII intakes with a 3-bolt pattern. It would flow better than the 90mm setup but I'm told the power gain is negligible.
The NW 90mm is in teh $400 range. I just ordered mine from Thunder because I was tired of hunting and I order stuff from Tom when I can.
