This is what all big-block crate engines should be: maximum power with a maximum return on your money invested.
We started with the 454 that everyone loves and pumped it up to a 502 cubic inch powerhouse that delivers gobs of low-end torque and top-end horsepower.
Even though the 502 is a great value, don’t think for a minute that we skimped on parts or validation of those parts to the highest standard in the industry. The 502 HO bottom end consists of a cast iron four-bolt block, forged steel crankshaft, forged steel connecting rods that have been shot-peened for durability, and forged pistons. A high-lift roller camshaft controls the airflow through our legendary rectangular-port cast iron cylinder heads, more than enough air to fill those hungry 502 cubes! One other key engineering feature is that the final compression ratio comes in at 8.75:1, so that when outfitted with our 502 HO, your performance GM car will make tremendous power from just pump gas.
GM Performance Parts has completed this amazing crate engine with an aluminum dual-plane intake manifold, cast iron water pump, 6-quart oil pan (with windage tray), damper, and a 14" flexplate. Pick the carburetor, starter, and ignition system, all available from Friesen Chevrolet Parts, and you are on your way to big-block bliss.
