ALL  CRATE ENGINE - Part Number 12568778
Crate Engine 502 HO. Highlights: HP: 450 @5250 rpm TQ: 550 @3500 rpm Gen VI iron big-block with 4-bolt mains Iron rectangular-port cylinder heads Dual-plane aluminum intake manifold 8.75:1 compression ratio High-lift roller camshaft 6-quart oil pan with windage tray Cast iron water pump Balancer Black, ribbed valve covers Ground-pounding large-displacement value. There's nothing quite like the tug on your back as you dip into the torque generated by a big-block V-8. And with the 502 HO, you can experience the axle-twisting torque created by GMPP's legendary 502-cubic-inch Rat engine at a more economical price. The 502 HO is filled with a 4.00-inch forged crankshaft, 4.47-inch forged aluminum pistons, forged rods and a high-lift steel roller camshaft- all ingredients for durable, count-on-it performance- and it's all topped with a set of rectangular-port iron cylinder heads. The 8.75:1 compression ratio is pump-gas friendly and makes the 502 HO a great candidate to be upgraded to a supercharged street engine too. GMPP finishes up the assembly with an aluminum dual-plane intake manfiold, cast iron water pump, 6-quart oil pan (iwith windage tray), damper and 14-inch flexplate. You finish it off with a carburetor, starter and ignition system - all available from GMPP. With 450 horses and 550 lb. ft. of torque, the only thing the 502 HO sacrifices is cost. Installation Notes: Requires addition of carburetor, fuel pump, starter, distributor and ignition system. Clutch linkage boss is cast into block,but must be drilled and tapped. When using cast iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads, for clearance. Requires electric fuel pump because the Gen VI block has no mechanical fuel pump boss. Comes with a 14-inch automatic transmission flexplate; use flywheel P/N 14096987 and 11-inch clutch assembly for manual transmission. Not intended for marine applications.
