This engine features a standard deck height “iron” block with four-bolt main bearing caps, a 4.00" stroke forged steel crankshaft and 4.47" diameter forged pistons.
The compression ratio is a reasonable 8.75:1 when used on the 502 HO engine, with 118cc chambers cast iron heads, or 9.6:1 on the 502/502 HP engine with 110cc chamber aluminum heads. It has 4340 steel connection rods with 7/16 rod bolts.
This partial includes block, crankshaft, pistons, flex plate, damper, oil pump, oil pan, front cover and steel roller camshaft with lifters. (When replacing the 502 HO engine, the camshaft must be changed from 12366543 to 24502611.)
