Affordable Big-Block performance with huge torque and 461 hp

With 461 horsepower and 558 lb-ft of torque, our 502 HO crate engine has power on tap for every need — whether it’s a ’69 Chevelle at the drag strip or the Suburban that towed it there.

 

The 502 HO is all about torque and it hovers at the 558 lb-ft mark at only 3400 rpm and arcs gently above the 500 lb-ft level by 2800 rpm, remaining there through 4200 rpm. All those axle-twisting pound-feet are rooted in a stronger, updated four-bolt cylinder block that houses a forged steel crankshaft, forged and shot-peened rods, and forged aluminum pistons. In other words, it’s a super-stout assembly that is as durable as it is powerful.

 

Iron, rectangular-port cylinder heads keep the 502 HO affordable, and our crate engine assembly includes an aluminum dual-plane intake manifold, a water pump, 14-inch flexplate, balancer, and more. You add the carburetor, starter, and ignition system
