GM Performance GM12498772-AF Chev Sb 383 Dressed Crate Engine Alloy Heads 420 Hp 440Ft/Lb

Item Description

This 383 delivers Big-Block-style performance.

Using the sturdy 383 bottom end including four-bolt mains, a forged crankshaft and heavy duty rods, we topped it with Aeroflow Aluminium cylinder heads to enable 420hp and 440 lb-ft of torque. The Aeroflow heads use high-flow 200cc intake runners, 2.02/1.60-inch valves & 64cc combustion chamber design to process air quickly and efficiently. A roller camshaft with more than 0.500-inch lift on both the intake and exhaust sides helps this potent engine maximise airflow. It is complemented by friction reducing aluminium roller rocker arms.

This crate engine package includes; Holley 750cfm vacuum secondary carburettor, Performer Air Gap manifold, MSD Distributor, Flexplate and Harmonic Balancer. With this 383 crate engine, you get the best of both worlds Big-Block power with Small-Block efficiency.
