Build BIG Modular Power. The Ford Performance 5.3L Modular Stroker
short block is a great way to build modular power - from mild to wild -
naturally aspirated or supercharged - 2 valve - 3 valve or 4 valve.
Ford Performance
Engineers have taken care of the toughest part of building a new engine
by designing a strong and durable shortblock that offers a wide range
of power possibilities. Ford Performance uses only the best parts,
starting with the BOSS Modular block, and adding forged Eagle steel
crankshaft, forged Eagle H-beam connecting rods with floating piston
pins, and forged Mahle pistons. Bored and stroked to 5.3 liters, this
short block is precision internal balanced and ready to be finished to
your specific application.
