I found a 96 cobra block with 17k miles on it, but it was involved in an accident.
"Apparently", the motor mount was jammed up into the skirt of the block, making a crack in it. Since it is a teksid aluminum block, it should be able to be welded back up... but also since it is an aluminum block, couldn't the force of that impact have damaged everything inside??
I'd shy away from a cracked alum block. Yes it can be welded... im not sure which aluminum a teksid is actually made of but the actual crack is probably a simple repair. The issue is that aluminum blocks have very tight tolerances compared to iron. its possible that some of the geometry was offered. If you're considering this for a full rebuild where you can blueprint it and check the deck, Id say go for it as long as you check the crank rotation and everything feels smooth. Check with and without plugs for compression and ease of motion. I wouldnt look at it if you just wanna weld the crack and try to run it. unless its just a stupid good deal.
