Ford RacingWith Ford Racing Performance Parts, you can still go right to the factory for a small-block crate engine. Before production of the Windsor 5.0 ended, Ford Racing ordered a supply to use as a foundation for its popular M-6007-XB3M and XE3M crate engines. Rated at 345 and 340 horsepower respectively, the engines are new 5.0 short-blocks fitted with GT-40 aluminum heads and either a B303 or E303 roller camshaft. Finned aluminum valve covers are included as well as a water pump, but the pump is a reverse-rotation version for late-model serpentine belts and must be replaced for vintage V-belt systems. Likewise, you'll need to replace the Fox-body oil pan with one for an early Mustang.
By stepping up to Ford Racing's 347 stroker, PN M-6007-C347, you get a new Sportsman 5.0 block, Z304A aluminum heads, Edelbrock Victor Jr. intake, and MSD billet distributor for a rating of 450 hp. With the same external dimensions as a 289/302, the C347 stroker will drop right in a '65-'73 Mustang.
Ford Racing also offers a number of 351s, starting with M-6007-S58, a low-buck 5.8L with cast-iron heads that comes from Ford's marine-engine program. Also available is the 385hp D351ST with aluminum GT-40 heads and the stroker 392ci D392FT with 430 hp.
