i have a shaner s2 ported throttle body and i like it very much.it also had the bump stop mod already done to it.i think it was 175.00 plus a core charge for the old one.

 

BBLS1 I don't know about your truck, but my throttle body is the same cast as an LS1 throttle body.

 

slow4.8, if you ever get into the fort worth area let me know and i'll let you look at a few of the ported throttle bodies i've done. it's pretty easy to do, and with the right stuff you can actually make it look pretty professional. and the LS1 and TRUCK tbs are pretty much exactly the same.
