Maybe relatively new motor had the WRONG damper on it ?
Or maybe it had an External damper that had slipped a lot ?
External when it should've been Neutral ... or vice versa.
Maybe the damper bore was too loose?

Not necessarily the crank per se, it just didn't wanna run right. I can't remember exactly what the issues were.

I went back and looked at some of his posts - here's where he got the 383...

"Buy a 383 stroker from S&J engines in Spokane. Got mine for $2300, remanufactured long block with roller cam"

The Bitterness of Poor Quality remains Long after the Sweetness of Low Price is Forgotten.​

Darn, going to have to say good-bye to GMT-400. Broke the crankshaft in my relatively new 383. As the Suburban is 30 years old, wife doesn't want to fix it, so its a parts truck now. She wants a newer truck. The sad part is that I put a lot of money into it to make it the ultimate tow vehicle. Went to start it a few days ago and ran really really rough. Shut it down. Thought it might be a loose plug wire, but all were connected. Tried again and was rougher then heard a big crunch, the harmonic balancer broke off of the front of the crankshaft. Then it ran better but the serpentine belt wasn't turning. I knew it was over, so sad. Enjoyed working with you all and thanks for all the help along the way.
Blame it on the wife. Good one. Just say you are tired of it and want a new toy.
