LS2 in Burned out Trailblazer SS 
We were searching the junkyard today for Nova parts and came across a Trailblazer SS that had caught fire ,but the engine was still in the car. i was wondering if the engine would be safe to take and rebuild and use in our Nova. Can somebody help me out?
We are mostly after the heads but if the engine would be okay to build then we thought about buying it

That looks like one helluva fire man. I would be a bit skeptical about using anything from it. Maybe the bottom might still be good though. May be worth the purchase just to disassemble and assess from there.

Due to the fact that NONE of the aluminum parts on the outside of the motor are melted, the inside will be fine with some work. The heads will need a valve job, new seals and get new springs while your at it. None of the plastic **** is fit to use but the internals of the motor won't be hurt.

Bullshit. Look at everything melted on top of the heads. Imagine that intake melting and going down the ports. Not including everything else thats melted inside the block like knock sensors, valley cover parts, cam crank sensors, Rubber seals etc. That **** is toast period.
If you wanna **** money away on buying a pile of burnt *** paper weights I can sell you some of those!

Plastic melts at a much lower temp than aluminum and last time I checked plastic doesn't adhere to aluminum. We already chipped at the plastic and it comes off. We can replace seals and sensors. I saw no evidence of fire in the engine bay just heat related stuff. It was a fire in the interior.

i would imagine the temps it reached internally due to the fire would be know more than what it sees during normal running of a combustion engine. the damage would be on the outside of the block. for the right price, id be all over it

For $150 for the pair plus the cost of a valve job would be around $450 total. It's still a savings of $350. GMPP sells them for $378 each brand new.

id offer 100 bucks for the engine. take it home and dissasemble it, as long as the block, rods, crank and pistons check out at a machine shop have them rebuild it for about 900 bucks. and you can melt the plastic back out of the heads and off the block for that matter its no big deal once you tear it all apart and clean it all up its worth 100 bucks to check it out

Interior fire? Lol. Melted the rubber out of the damper. If it hasn't been covered, it's full of rainwater. Walk away, bro. I wouldn't haul it home if it was free. I had an opportunity to buy an ls3 out of a camaro that had an interior fire, with under 10k, and it Had a melted intake, and coils. That blazer your looking at has been very, very hot.

Nonsense. If the hard parts are good, and you can get it for a decent price, go for it. I pulled an ls1 out of a camaro that had an engine fire and spread all the way to the rear bumper before it was put out.
The fire was so hot the valve covers started to melt. I drained 8 gallons of water out of the engine after I pulled it. Guess what? Everything south of the valve covers was fine. Had the heads milled and the bores honed and it's still running 4 years later.
