Strong 318

Stock strong running means a high compression version from the late 60s or so. I cannot remember a 4bbl factory version in that era.
IMO you'd be better off looking for a converted Magnum, or a built LA.

OOPs; it says "good running" not strong-running, sorry.
OOPs title says "strong", so back to the top,lol., but add;
Or a sucked out 360,lol
