Fits On/Installation Notes:

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 1,500 rpm and arcs gently above the 500 lb.-ft. level by 2,800
rpm, remaining there through 4,200 rpm. All those axle-twisting lb.-ft.
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

550 lb.-ft. @ 3,500 rpm
450 hp @ 5,250 rpm
