Thanks, Rich; I'll try to get his attention over there... and thanks for the explanation.

The 318/340/360 motor has some dimensions (taller deck/longer rods, higher cam location, compared with a SBC) that allow it to use a 4" stroke without interference, so several companies that deal in aftermarket hard parts (SCAT, EAGLE, etc.) started selling 4" cranks for these engines a couple of years ago... maybe longer.

Some of them are cast; some are forged, and a lot of the cast ones come from CHINA... 'nuf sed.... but they're incredibly cheap ($239.00)

Sometimes, you get what you pay for... lol!
