Product Description

A Big-Block for Your Truck and it’s Compatible with Gasoline, CNG, or LPG!
When it comes to grunt work – like pulling your car hauler or offshore racing boat – Chevrolet Performance’s new, heavy-duty 8.0L Big-Block does the job like no other engine.

This latest edition of the classic Big-Block is all about torque and makes up to 475 lb.-ft. (on gasoline) by only 3,200 rpm – and maintains a smooth, flat and useful torque band across the entire rpm range. That gives your truck the power to pull just about anything and flatten the steepest grades.

The 8.0L is built with a tall-deck (10.2-inch deck height) version of our latest Big-Block casting, which features full-length water jackets, thicker main bearing webs and four-bolt main caps. It also uses a forged steel crankshaft and forged connecting rods for optimum strength. A long, 4.250-inch stroke helps maximize the torque.

This modern Big-Block is equipped for a crank-triggered ignition system and features a 4X camshaft and 58X crankshaft reluctor wheels to support it. The engine can support fuel injection and also has a provision for a mechanical fuel pump.* Our assembly comes with heads and a balancer installed. An induction system, ignition, starter, water pump and other accessories are required to finish the engine.

NOTE: This engine requires an intake manifold designed for a tall-deck block. Chevrolet Performance intake manifold P/N 88961161 was used in development. Conventional big block intake manifolds can be used with spacers (not included).

*Production 8.0L camshaft does not have a fuel pump lobe.
