Well, I got a 350 off craigslist out of a 98 silverado for my 350 swap, the guy said it ran great with about 95,000 miles if i remember right.. i bought it last year, and the last couple weeks i've been fixing it up buying all the parts i need to drop it in. Well i got the vortec heads redone to handle my lt4 hotcam and noticed the pistons had .060 stamped on them. The block numbers were 14093638, so its not a 98 block. And finally I took the oil pan off to paint it and new gaskets and everything and found a broken crankshaft... Im thinking i was ripped off, Heres a pic, What could cause this??

 

Orange paint. J/K It could be many things.

 

Jeeze its red, and i put hard work into that paint job lol

What could cause this??
well, incorrect clearances, a defective cast crank, or a badly balance rotating assembly, a defective balancer, are factors that jump to mind but a detailed inspection once its all apart will give you a good deal more info. you obviously were LIED TOO, that engine could not run in that condition without making one hell of a noise so obviously you were sold a busted engine knowingly, buy the seller, thats why your never supposed to buy an engine without hearing it run or pulling the heads and oil pan for an inspection to verify your not buying a trashed engine from some smiling lying bastard out to scam you!

 

Hate to throw the blame your way but it takes less than 5 minutes to pop the oil pan off a motor prior to buying it and you'd have seen that... It should be common knowledge to never trust people's word in these types of situations.

 

Yea I definitly learned my lesson on that, I had my dad pick it up for me when I got it, but next time I will know better. Anyways, I have it all torne apart now and am going through everything and figure out what I want to put back in it. On the plus side the pistons are .040 over not .060 and the block looks good.
