I picked a stock stroke 351W.

The popular stroker when I was having the engine built ('97) was the 377W. Used offset ground stock Windsor crank, Mopar 360 rods, Chevy (283?) pistons. Machinist wasn't real keen on the combination.

Machinist recommended hydraulic roller 351W would emulate 400W, and he was right. The other option was the 408W. This used Ford 400M crank that needed a lot of machining and balancing to work, and leaned toward low end torque. As a truck, van, or station wagon motor, this would be ideal. For a lightweight Cobra, it left a lot to be desired.

Today, Scat (among others) make a crank and rotating assembly designed to replace the OEM Ford pieces. Even Ford Racing has picked up on this and offers a crate motor 392 with all the above good pieces.

But Ford Racing, or Ford Motorspotts, shoots itself in the foot by using overly flow restrictive heads, and too much cam (to make up for the flow restriction) for street use. So, buy the short block, and talk to the guys at AR, TFS, Ede, about head and cam combinationns that work.
