I have a GM 1053 forged steel one-piece rear-main-seal crankshaft that has been ground to 3.50" stroke. These are rare and were reportedly only installed in ZZX crate engines, which is how I got mine.

Don't worry too much about the added stroke messing up deck height, as the piston only goes .010" higher in the bore, so it only helps you unless you're already zero-decked. Even then, you could run a thicker head gasket.

Here is GM's description, part number 14096036:

$200 or best offer.

I'd rather not ship, but if you're willing to foot the bill I'll do it.

That's a smoking deal. I bought one of those bastards many years ago for more than 3x that from GM.

 

Wish you would have posted this a Month ago. Already had my crank and pistons ballanced..... Good luck with the sale.
