The older 351W's as they came from Ford were nothing you'd want to put in a Cobra. They're not called Fords' Truck & Boat motor for nothing. As a base block for a motor using todays components, it's an entirely different story. The popularity of the 302/5.0, and the interchangability of some of the 302's parts onto the 351W have resurected the stodgy old Windsor from its' Boat Anchor status.

You want a good core block, and not much more. $ 100 - $200 is all you want to spend here because all you'll be using is the block and front timing cover.

You could re-use the rods. They're forged and OK for a street motor if you recondition them. Weigh the cost of the reconditioning, vs already reconditioned Stage II rods, vs new aftermarket forgings. How much time will your engine spend between 6000 - 7000 RPM will determine your choice.

You could re-use the crank if you want to leave it stock displacement. A 393 stroker crank will add $450 - $550 to your build cost. The stroker uses the stock rods, and you need a set of pistons anyway.

Pistons, forged or hypereutectic cast (specifically Keith Black pistons made by United Machine, NOT OEM replacements). The KB's will make a better street motor. Forged tilts the scale toward abuse resistance. Both have specific pistons for strokers.

Have your machining done by a competent engine shop, and ask the machinist for his recommendation on components. You might be surprised at some of the recommendations that vary dramatically from the advertizing hype. I was. One was, "Don't use aluminum rocker arms on a street motor." Be prepared to answer this one question as truthfully as you can. "How do you intend to drive the car?" How much do you expect your driving habits to change from whatever you're driving now?

Food for thought. This little car is quick and nimble, and I do tend to drive it more "Spiritedly" than the family grocery getter as you will. The engine powerband is definately 3000 - 6000 RPM, but most of the driving is off idle - 3000 RPM, with 2500 RPM highway cruise. (So, in retrospect, I could have used a few more cubic inches, and a little less cam)
