Ported TB worth the $?
Agreed. It's actually only $180 shipped for a brand new powerbond. The extra $20 is for the ARP bolt. The best time to do it is with a cam swap though since you'll probably have to pull the radiator to fit the puller in there. My car had one on it when I bought it.

Hijack! Since you guys are talking about ported TB's, I had a quick question. I'm finally getting LT's, ORY and a tune installed in two weeks. I was also interested in getting my TB ported but I only have the stock LS1 manifold for the time being, I'll eventually grab a LS6 down the road. Is it worth it to port my TB with the stock LS1 manifold?

cammed/bolt on ls1 with ls1 intake

exhaust, cai 5.3 Silverado
It takes me about half an hour or less to do one with a dremel and a carbide followed with a sand roll. I would spend the money on the dremel and a set of cheap bur bits on ebay before I would pay to have it done.

And what about these motor mounts? I keep hearing if you're putting LT's, then you have to replace the motor mounts since they're so old. Will the shop automatically do it if it's the obvious or should I mention it?

I would buy the motor mounts and provide the shop with them. I remember I went to Lous exhaust and had to tell them to do the motor mounts. Then they continued to hack up my exhaust. Unless your shop is a sponsor on ls1tech then they would already know.

Speed, Inc. is doing it and they are a sponsor.
I'd still mention it just to be sure. I mean, they could just skip it thinking you'd be the opposite type of customer; that is, "hey, why'd you charge me for new motor mounts?! I didn't tell you I wanted new motor mounts!"

How much do these motor mounts go for? And say if they didn't replace them, what's the possible damage in the long run?
~$50. I don't think it's so much about damage by not doing them; rather, it's so the long tubes will fit and the exhaust won't bang around. The theory is that even the newest factory motor mounts are now 11 years old...
I would do the motor mounts, its not worth possibly having one fail down the road and having to redo the exhaust work. As far as the TB do it. Mathematically there should be some power since there is increased CFM, but the response is the main thing
+1... Just do the mounts...

Good question...I'm not sure? I went with a recomended Cam from a speed shop, I misplaced all the paperwork and the speed shop has since shut down. I just know I lost power in low RPM's but once she hits above 4500 its awake! Is there anyway other way to find out the specs beside pulling the cam?
Yeah I did it because I was bored and wanted to spend money. It did crisp up the throttle response a bit but you get used to it fast and then it's off to the next mod.
