After you build a serious 347 cubic inch Ford 5.0—like we did in our first installment of Project Strokers Wild—what do you do for an encore? You build it a bigger, badder brother.
In this second installment of our Stroker’s Wild engine series, we’ll show you how we built a 393 cubic inch 351 Windsor. The big advantage of a 393 is size. The engine’s extra 42 cubic inches mean power, and lots of it. Need low- and mid-range grunt for a street car or for towing? A 393 is a veritable torque monster. Horsepower? Properly built, a 393 can make an easy 450 to 500 horsepower. And it’s all in a package that will fit under the hood of a Mustang. Well, a tall hood.
A 393 can be pretty inexpensive to build, too. The only custom piece is the crank—the rest of the combination uses a .030-inch overbored stock block, stock length 351W rods, and stock-type 302 pistons. If you’re conservative with the rest of the engine, you can get those extra 42 cubes for just a few bucks more than a stock-stroke 351W buildup.
We built our 393 with a Summit Racing cast stroker crank and H-beam connecting rods, Trick Flow 10:1 forged pistons, a Crane roller cam, Trick Flow Twisted Wedge Race 225 aluminum heads, and a Holley 750 cfm double pumper carburetor on an Edelbrock Victor Jr. intake manifold. The Summit Racing crank is no longer available, but you can duplicate our build using a SCAT Series 9000 crankshaft instead. Check out the parts list below–you’ll see how easy it is to build a hot stroker Windsor of your own!
