Affordable Big-Block performance with huge torque and 450 hp
With 450 horsepower and 550 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. It hovers just below the 500 lb-ft mark at only 1500 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 — all available at chevroletperformance.com.
