New at Summit Racing: Ford Performance Parts 5.3L Modular Boss Short Block Engine

Building a killer Mod motor just got a lot easier. Ford Performance Parts’ 5.3L Modular Boss Stroker Short Block is the perfect foundation for any 4.6L-based engine. Just add your cylinder heads—2-Valve, 3-Valve or 4-Valve—valvetrain, an induction system, exhaust, and ancillary parts and you’re ready to go. The Boss can even handle superchargers and turbos.

The Modular Boss short block is bored and stroked to 5.3 liters, and comes fully assembled from the Ford factory with the good stuff:
• Ford Performance M-6010-BOSS50 cast iron performance block
• Eagle Specialties 3.750-inch stroke forged steel crankshaft with eight-bolt flywheel pattern
• Eagle Specialties 5.850-inch forged steel H-beam rods with ARP 2000 bolts
• Mahle forged aluminum dished pistons with floating pins, compatible with 2-, 3-, or 4-Valve heads
• New high pressure oil pump
• Neutral/internal balance rotating assembly
• Assembled and ready for your heads, cam, and timing set

If you’re in need of cylinder heads, Summit Racing carries Trick Flow Twisted Wedge series 2-Valve aluminum heads and Ford Performance Parts’ 3-Valve heads.
