Thanks, but mine is 3/4 ton, so I've got the iron block 6.0, with no AFM. That said, I thought trailblazers only sported the I6 vortec 4200.......TB with a v8 has some balls I bet!

Tbss comes with 6.0. They are fun. Think of that engine like a lq4/lq9.

drove it, and broke it.

started running rough while out running some errands. made it over to my buddys shop was smoking pretty bad out the tail pipe, lots of fuel smell. no check engine light but cyl #3 colder than the rest so we started there. pulled the plug checked spark, turned it over without the plug and whole bunch of full came out of the hole, injector seems to be stuck wide open couldnt find one local so wont be here till tomorow. scoped the cylinder doesnt look all that great but going to swap injector and see what happens.

had set up to get realigned and rear pinion seal swapped tomorrow dunno if im going to have to put that off now

Took the burb to one of the trusted motor rebuild shops around here. The owner thinks its the main bearing. So, with them, options are 42-4500 to rebuild, or 6200 for a re-manufactured motor.

Going to stop by my mechanic and see how much he would charge to put in a new motor that I would have delivered. Found an LY6 on lowmileageparts.com for 3k. They have a decent warranty, but outside of that I'm not sure of their rep. If I choose to go that route, I'll just drive it till either it blows, or until the motor comes in stock.

This is what you need.

You're goddamn right I do. I asked my mechanic about retro fitting an 8.1 into it awhile back...he said it probably wasnt a good idea. Not to mention the stuff from that site is bare bones...I'm sure I'd need all the computers too...

Drove around in a rain storm, trying to locate the source of water in my driver's side floorboard. I've scoured the webz (seems a common problem) and still can't find where it's leaking. Damn it.

This guy spells it all out pretty good.

It basically bolts right into the 3/4 ton GMT900 because they use the exact same chassis as the GMT800.

Nope. My hole lies elsewhere.
