If you want big block power for your ride but want to have a say in the final product, GM Performance has the solution. Their 502 c.i.d. short blocks can be configured to deliver all of the muscle you want. The heart of these powerhouses is the same short block that GM uses for their 502 c.i.d., 502 hp bruiseraso you know they can crank out the power.
Chevrolet starts with a Gen VI 4-bolt main block with a one-piece rear main seal and priority oiling for the main bearings. To that, they add: an externally balanced, forged crank that's shot-peened and magnafluxed; forged steel "dimple" connecting rods; forged aluminum pistons; a single-roller heavy-duty timing chain set; and a hydraulic roller camshaft.
The cam has 0.527 in. of intake lift and 0.544 exhaust lift, with 110 degrees of lobe separation. Duration at 0.050 in. of lift is 224 degrees for the intakes, and 234 for the exhausts. These long blocks come complete with a powdercoated cast aluminum timing cover (will not accommodate double-row chains); aluminum cylinder heads and valve covers; a 6 qt. truck-type oil pan (will not fit Chevelle, Camaro, Nova, or Impala); a 14 in. flexplate; and an 8 in. harmonic balancer.
