I'm not sure about the others, but a TBSS and a G8 have two belts, one for the a/c and one for everything else. That then would not let them interchange if the ls4 only has one belt. Look around for another ls moter that only has one belt.
iv been looking around and cant see why this shouldnt be possible ..would do you guys think??
would these work?

FWIW, here's a comparison of the LS2 accessory drive vs LS4. Big difference. This shouldn't be too hard for an aftermarket company to adapt and make for you guys. You should try starting something similar to whats going on with the header situation.

Verdad Gallardo maybe we would have better lucky looking at a 6 groove setup off a 3800 v6 or something havent looked it up yet just a thought .. and for the alternator, maybe off a truck setup.

The reason they wont work for us is our crank and assessory are a shorter leangth than any other LSX. And from what i can think every other LSX based motor uses two belts. And as for the sensativity of our pulley system. Havent we had a couple people with HUGE issues when doing some mods and have the pulleys way out of alignment????
the only problem i had is getting the belt back on .. its a nightmare! at least without the proper tool.. and wen my water pump was going.. it ate belts like there was no tommorw..
What type of tool is required? I was looking at my dad's 08 gxp and it does look like a nightmare. Where can I get the tool? Is it available at a local parts store or only through snap on?

your best bet is to do a group thing like what was done with the headers. They are a good mod for the LS engines, typically pick up around 10hp. Not bad for a couple hundred bucks.
I contacted march performance and the said I could use a pulley made for a v6 camaro just had to check pulley offset and diameter . But should work with a single belt 6 groove setup
