Well then, let me confirm it, so there won't be any confusion: No, you cannot use your old crankshaft with a 383 stroker. Or pistons, either, for that matter. Different compression height.

Rev the *** out of the L-82 with a forged crank. I do. And when I go 383 or 427 it will be all forged.

I didnt see were the op was going cast. Forged cranks dont cost that much more. like i said before, If its the original l82 block id moth ball it and start with a 4 bolt block.

Scat has a stroker clearenced assemblie, internaly balanced, forged and iirc you can a standard base circle cam. You or the machine shop will still have to clearence the block and check the crank through to cam clearence.

the L-82 blocks are all four bolt mains. the short block is identical to the 71 and up LT-1 block except for the cam.

I thought that but would save it and find another 4 bolt block to build. If it was a l48, i wouldnt care but l82 being a little more collectable.

Cast crank and hyper pistons, but damn, the price is right. And I would bet that it would hold up just fine in a 400 HP, sub 6000 rpm engine. Just to keep things in perspective.

Also, I think a brand new cast crank, made using modern production methods, might be a lot stronger than a 40 year old one. Is there anybody out there who knows a little metallurgy who would care to comment on that?

People push cast assemblies with hyper pistons, some live and some don't. Im a forged fan for any performance application for 2 reasons, the first being piece of mind, if I'm gonna spend money and put forth the effort I want a solid foundation, hypers don't hold up well to tuning errors, the second being that I'm never satisfied, I want more and a forged bottom end allows for room toexpand some. While a forged bottom isn't completely nesicerry for some, others such as my self get bitten by the bug and more is never enough. Jmo.

I have to admit, that's a great point. It's better to have it and not need it, than to need it and not have it.
