Crate Engines

LS3 - 525HP With Chevrolet Performance’s aggressive ASA camshaft – developed for the high-rpm world of circle-track racing – installed in the LS3 6.2L engine, it comes alive with 525 uncompromising horsepower. That makes it the most powerful naturally aspirated 6.2L street engine in our

ZZ6 EFI Turn-Key - 420HP

portfolio – and one that has an edge to it. You’ll notice it in the idle quality and you’ll feel it when the revs quickly climb.

The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm. And for durability, we complement the cam with higher-rate valve springs. You’ll need tuning to make the most of the engine in a late-model GM vehicle. If you plan to use the engine in a vintage car, you’ll need controller kit P/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.

The ZZ6 EFI Turn-Key crate engine offers modern performance balanced with tradi tional style that looks period perfect in your vintage Chevy! Chevrolet Performance engineers adapted a unique, electronically controlled port fuel injection system to the ZZ6 350, using an aluminum intake manifold that has the appearance of a carbureted intake. A fuel injection throttle body mounted in place of the carburetor allows a traditional air cleaner to be installed on the engine. A simple plug-and-play control system rounds out the package to get the engine running in your project without the need for third-party tuning. Our Turn-Key crate engine kit includes the distributor and damper installed, with the throttle body, starter, air conditioning pump, alternator, single-belt Front-End Acces sory Drive Kit and more also included. Chevrolet Performance also offers the ZZ6 EFI Deluxe kit, which includes the installed distributor and damper (P/N 19368149).
