Important Notes

Original items such as manifolds, accessories, mounts, etc. can be transferred to a ZZ502 deluxe engine when installed in a vehicle that was originally equipped with a big block. However, there may be some dissimilar components between a ZZ502 deluxe engine and an older big block.

Installing this engine in a vehicle not originally equipped with a big block engine may require modifications or additional components not included, such as fabricating various components for the cooling, fuel, electrical, and exhaust systems.

Chevrolet recommends using a minimum octane rating of 92 (R+M/2) fuel in the ZZ502 (9.6:1 compression ratio) to prevent pre-ignition.
