383 Stroker??????

[bigscoobie]

Can someone please tell me if this is a scat 400 crank or crank for a 383 stroker?

There aren't any other numbers on the crank? I'm not finding anything online. Mine was at the rear flange, but then again it was a factory GM number.

A 400 crank will have a 2.65" main journal size and a 383 will have a 2.45" main journal. So that being said the 383 crank will only work in a OEM 400 block with main bearing spacers and the 400 crank will not fit in a 350 block without having the main size cut down. In your pics the crank is in a block. What block is it in?
