I recently saw that Speed-O-Motive has a stroker (3.55" stroke)kit for the 4.3L V-6. Does anyone know if any companies produce a 3.75" stroke crank for the 4.3?

Are there any others? I know that GM used to cast a semi-finished that can be finish-machined to a variety of different strokes. Do they still sell these?

That was the crank that I mentioned in my original post. It's 3.55" stroke but I'm looking for a 3.75" stroke.
