The GM Performance Parts ("GMPP") Anniversary Edition 427 Big Block is the most exclusive crate engine that we've produced in the fifty year history of the Chevy big block. This all–aluminum, all–new crate engine is our tribute to the classic ZL1 big block – originally built in 1969. Using the same block tooling as the original, it's a modern version of the ultimate factory Chevy big block.
With so much interest, so much anticipation, and so many fans of the all–aluminum Chevy big block, we put together a list of the most common frequently asked questions to help get you the information you need on the hottest crate engine in the industry.

Like the Anniversary Edition 427, the ZZ427 offers a heritage earned through fifty years of big block Chevrolet development, engineering, testing, and racing. In addition, the ZZ427 features the same aluminum heads, valve train, and rotating assembly as the Anniversary Edition 427. While all of the components are the same, the ZZ427 will be rated at 480 horsepower.
Q: Do you make an air filter for the Anniversary Edition 427 Big Block crate engine?
