There are few engines that conjure up images of greatness like the 427 Chevy big-block. The ZZ427 big-block crate engine brings back all of the good things that you remember about the 427 with a few modern new upgrades. With an updated cast iron block, a 10.1:1 final compression ratio, and an aggressive hydraulic roller camshaft, the ZZ427 offers you outstanding performance while still living on low octane fuel.

The legendary 427" big-block Chevy powered some of the most storied cars in the history of the high performance automobile. This latest version holds true to that tradition, offering you a tough, 4-bolt main cast iron block with an all forged internal rotating assembly. The top half of the engine is aluminum oval-port heads that use 2.19" intake and 1.88" exhaust valves work wtih 1.7:1 aluminum roller rockers and a .527" intake/.544" exhaust camshaft. The intake is a matching high-flow aluminum oval-port piece. An aluminum water pump, spark plug wires, and a 14" flexplate round out the package. Internally balanced, the ZZ427 will spin to 6000 rpm before it's time for you to shift.

The ZZ427 is an exciting trip back to one of the high points in the history of the Chevrolet big-block. With a rating of 505 horsepower and loads of torque, it's still one of the best crate engines for just about any big-block application.

TREMEC's TKO series of 5-speed transmissions was first made famous by the 5-liter Mustang movement and has since been fitted into nearly every rear-wheel drive performance application imaginable.

Serving up 600 lb-ft of torque capacity, along with confidence-inspiring shifts and fuel-saving overdrive, the TKO offers an ideal blend of brute strength and street manners – which may be why it's the manual transmission behind more boulevard-bruising street machines and sportsman race victories than all of it's competitors combined.
