Project Strokers Wild (Part 2): We Build 393 C.I.D. Ford 351W
Slide Show
After you build a serious 347 cubic inch Ford 5.0--complete with ported Trick Flow Specialties Twisted Wedge aluminum heads and high-flow EFI intake-what do you do for an encore? If you're Summit Racing, 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. If you are just joining us, Stroker's Wild is documenting the buildup of three Ford stroker motors-the 347 cube 5.0L we did in the first issue, this 351W, and a 520 cubic inch 460 that will be coming soon. Then, we're gonna take all three to the dyno and flog 'em until they come up with some big numbers.
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" 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 cast stroker crank and H-beam connecting rods, Trick Flow 10:1 forged pistons, a Crane roller cam, Trick Flow R-Series aluminum heads, and a Holley 750 cfm double pumper carburetor on an Edelbrock Victor Jr. intake manifold. Engine builder Mark Lambacher figures this combo can get close to 500 horsepower. If you can't have fun with that kind of power, you can't have fun.
