School me, 3.79 strokers

I'm not thinking about doing one, but the 3.79 based stroker is something that I do not know the history of. it started when I found some pistons for a 3.79 on eBay a few months back, but noticed that they were fairly old stock. My guess is that the early stroker were regular cranks, with the rod journals offset, and turned to accept a Chevy rod. Add custom pistons, and your have a 3.79 stroker? If I am wrong, please let me know, I'm just trying to learn here.
FWIW, the 4.00 are stroker would be easier and cheaper being more popular. MoPar also used to have a pretty good verity of stroker cranks. A popular trio is/was the NASCAR 3.5 area cranks.

IIRC, I could be wrong here, but *I Think* they were available for the 340 & 360 journals. These 1043 forged cranks could be a available at a reasonable price BUT pistons may end up being expensive and custom. Also, IIRC, there 8 bolt flanged.
