Just a few short weeks ago we brought you the announcement from Ford Racing of the new Big Bore BOSS blocks. It hasn’t taken long for the speed freak engineers to take advantage of the massive cubic inches that these blocks can hold and introduce a new crate engine based around one of them.
Packing 460 cubic inches of small block Ford fury, the all new Z460 crate engine is the most powerful small block crate engine the blue oval has offered to date.
Using the maximum potential of the Big Bore BOSS 9.5 deck block, the Z460 has a gaping 4.150-inch bore, and monster 4.25-inch stroke. Packing only the best forged internals, Ford Racing uses SCAT forged H-beam rods, and a forged SCAT crank, to pump a set of 10:1 MAHLE pistons. While Clevite bearings make sure it all glides smoothly.
The hydraulic roller camshaft features 242/248 duration at 0.50, and lift is a burly 5.94/6.18, no doubt the Z460 will shake the pavement wherever it goes. Topping it off are a set of the proven Ford Racing Z304 heads, with 2.02 intake and 1.60 exhaust valves. Controlling the oil is a deep nine-quart rear sump pan with windage tray and crank scraper.
Testing with an Edelbrock Super Victor intake manifold, Holley 850 CFM carburetor, and long tube headers has shown 575 hp and 575 ft-lbs of torque, stump pulling big-block level grunt from a small block package.
Part number M-6007-Z460FRT is available now as a rear sump or order M-6007-Z460FFT for a front sump. We can think of a few cars we’d like to drop one of these bad boys in, how about you?
