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.
