I have 2 crankshafts that were stored in a building that burned to the ground. Both had been machined and were ready to use. Obviously they need cleaning, machined again, etc.
My question is are they useable if they can be turned again (not bent)? I'm no metallurgist, but would the heat from the fire have caused any irreparable damage? They are a forged 440 crank and an old crank from a mid/late '50s Chevy 283.

I don't know how hot it got, but there was nothing left of that building but metal and concrete. Anything aluminum was reduced to a puddle on the floor. Guess I'll clean them up and see how they look.

I put the old Indy headed motor that used to be in my cuda into it. Just never completely finished it to race, but it does run and drive.

Thanks yall. It could have been a LOT worse. My dad's house wasn't damaged at all. His '69 road runner (the 4 speed 6 pack car) was parked at his house, so it is fine. The cuda and the Demon were in the shop and they are perfectly fine...as is the shop. The fire burned around it...somehow. We had 3 trailers all parked side by side, right beside the shop. My enclosed car trailer only had one tire damaged by fire, my open car trailer burned completely (all 4 tires burned to the rim, leaf springs flattened, deck plates buckled, etc.), and my dads smaller utility trailer suffered the same fate. The '73 new yorker and the "old" '69 road runner were parked at the barn. The taillights will need replaced on both cars and the paint blistered on the road runner, but that's it.
Lawnmowers, three Honda 300 fourtrax 4 wheelers, and a bunch of car stuff got burnt up in the barn. Game room is a complete loss...pool table, weight set/workout equipment, more car stuff, etc. My old Ford tractor and Case backhoe are fine. One front tire burnt up on the backhoe.
Luckily a family friend saw it and called me at work. I had that big Duramax running down the highway that afternoon! I work about 25 miles from home and I'm not sure how I didn't get a speeding ticket. I saw the smoke from about 8 miles away and my heart sank. You can't imagine the relief I felt when I saw the shop was ok.

It does not take a lot of heat to warp a crank. I spun a rod bearing (#3) on my 440, which is close to the center main/thrust cap. Crank is discolored at this journal area.
In disassembling, there was a tight spot when rotating the crank. I pulled the center main cap, and the thrust bearing inserts. Tight spot when away.
I left the front and rear caps on, and put an indicator on the center crank journal. I had 0.010 run-out on the center journal.
I have not had it checked out yet, but my thought is it will probably take as much to fix it, than buy a new crank.

B3422W5...LOL, it's a shame my "spare" aluminum block was right beside these cranks and melted! DVW...possibly from a battery tender that was on a lawnmower. Gearhead...you're probably right. Cost prohibitive.
