Re: Much needed info.on Porting the LS1 TB
i've been working on that myself.
my dad has a machine shop (where i ported my TB) and i've been trying to pick up some cheap TBs to port and sell using a "core charge" method.
but they are not that cheap. least not for a weekend machinist like me.
besides the porting, i'd be doing the "bump stop" mod to make sure the blade was all the way open

mook99TA,
Yes I still want to have this done. the TB looks pretty darn good. I can send it out to you on Monday. So, Do you think you can do it for $40.00 even? I will send you my e-mail address if you can do it at that price. I don't want you to do a rush job but you say you can do it within a day and mail it back to me the next day right? I do want to have the TB ported and the TB bump stop done and maybe I can find someone local to do the polishing job.Thanks!

Re: Much needed info.on Porting the LS1 TB
Hey Mook. I have the same TB. I just take the blade assembly out when I ported it. Then, I marked off the ID of the TB, and cut off the top part of the bar that holds the TB blade in. After that I ground down the screws to match, I reassembled it and that eliminates half the thickness of the TB blade assembly and increases airflow

i've got a 2.5 hp buffer, i took a smaller cotton buff wheel and cut it to a little smaller than the ID of hte TB and just stuck it in there sideways and applied alot of pressure.

Hey mook99TA,
I sent you a PM for your address to send the TB out to you. Let me know if you got it so I can send it to you today or first thing Tuesday morning. Do you think I can get it back by Thursday. Let me know. Thanks!

Re: Much needed info.on Porting the LS1 TB
I all depends on how long it takes to get here. Depending on when I get it, it could be back in the mail the same day. I got your pm and sent you one with my address on it. If you know of anyone else that wants one done let me know.
