GMP-12496430-1 - GM ZZ430 Chevy 350CID 430HP Crate Engine
This product may require vehicle validation(s) for proper fitment. Please contact us to confirm correct vehicle fitment and usage.
This engine is based on GM Performance Parts limited edition ZZ430 crate engine originally produced in 1999.
The ZZ430 uses the time proven ZZ4 short block assembly that has powered thousands of hot rods, street machines, drag and circle track cars. Add to that solid foundation GM’s HOT Cam, which was developed by GM Motorsports for LT1 and LT4 engines used in showroom stock road racing. The HOT Cam specs were developed to insure long term valvetrain durability along with a broad and responsive torque curve. This cam is specifically designed for use with 1.6 to 1 ratio roller rockers.
Topping off the 430HP long block are GM Performance Fast Burn cylinder heads with all the components matched for use with the HOT Cam.
