I thought they were the same except the Efan and some tunning. I think the GTO's are the same but the alternator bracket. Could be wrong though.

Edit, and i know the intakes are differnt but thats not internal

Intake and exhaust manifolds are different. Internally, they're the same. The pcm tune is a little different too.

TrailBlazer has lower cam lift also in their LS2 like .500/.500 compared to .5xx/.5xx I think
.525/.525 thats why some guys with engine replacements find 25 more hp in the new GM crate replacements. LOL

This is a great thread. Very informative since LS2s out of TBSS seems to be a lot cheaper.

Right indeed.

And yes, the TBSS has a clutch fan.
No GTO or Vette LS2 should be priced higher than a TBSS LS2, where are you seeing the difference in prices? Is milage the price offsetting factor?

I dont think so. I remember seeing some guy selling 3 TB LS2s in the forsale thread and I believe he sold 2 of them to one guy for $4500. I'm not sure if that's shipped. I think that is extremely cheap. That is where I got the idea from.
