The Rat With 502 Horsepower and 567 Ft.Lbs of Torque!
The king of all big block crate engines is the ZZ 502/502, with
torque and horsepower that will have you grinning and your competition
wondering what hit them. This is as close as you will come to a custom
built 502 at crate engine prices. Additionally, this engine is full of
heavy duty parts, to ensure that it will be making awesome power for a
long, long time. With its forged aluminum pistons, forged shot peened
steel connecting rods w/ 7/16'' bolts, forged steel crankshaft, four
bolt main block, stainless steel valves, 6 quart oil pan, windage tray,
roller camshaft and big valve aluminum heads the ZZ 502/502 seems more
like a custom race engine than a crate engine.
