any other Trailblazer forums, also, V8 Swap question

Hey guys, i just wanted to ask if there was another forum out there that has good info on the trailblazer. Can you guys please post all the good forums.

Also, does anyone know where i can get info on swapping out the 4.2 motor with a V8 (maybe an LS1 or LS2 motor)? i know they make the envoy Denali with the 5.3, so i am sure a kit is already out there, just cant find it. they are also coming out with a trailblazer SS soon, so i am pretty sure it can be done. just need some good pointers.

Thanks for the help guys

PS i know, i could have just waited for the Trailblazer SS, but i am sure it would be over my budget.
