This combo was the 377 stroker, and was popular about 10 years ago. The crank was offset ground to a 3.61 stroke, and matched the Mopar rod journal. The Mopar 360 rods had to be milled on one side. This setup conviently mated up with 350 Chevy pistons unless you were using a '68 or '69 block. Then the pistons needed to be milled because of the shorter deck height. In short, a lot of machine shop $$$ (provided the machine shop was even familiar with this setup - most just gave you funny looks) for not much displacement increase.

The popularity of this pretty much died when Scat introduced the 393W stroker crank. It was designed to use stock 351W rods, and stock 302 pistons. Going the 302 piston route, the compression still needed to be dialed in by dishing the pistons. The stock rods could be reused given a typical warm street motor reconditioning. Again, the machining cost nearly equalled a set of new rods that needed nothing. Either way, it still needs balancing.

Today, the entire 393W rotating assembly can be had, balanced, with rings and bearings. FMS now sells the complete short block which includes sportsman roller cam block, stroker crank, forged rods, and (now) forged pistons. It lists for $3k. Pick your poison. Think these 393W's come standard in new SPF's.
