TRUCK POWER WITH GAS, CNG OR LPH
When it comes to grunt work - like pulling your car hauler or offshore racing boat - Chevrolet Performance's heavy-duty 8.0L Big-Block does the job like no other gas engine. It's designed to accommodate gasoline, CNG or LPG fuels, and because it's a Big-Block, it delivers strong, low-rpm torque.
A tall-deck version (10.2-inch deck height) of the latest block casting, featuring full-length water jackets, thickermain bearing webs and four-bolt main caps, is the 8.0L's foundation and it's used with a forged steel crankshaft and forged connecting rods for great strength. A long, 4.250-inch stroke helps maximize torque. It also features a crank-triggered ignition system, with 4x camshaft and 58x crankshaft reluctor wheels.
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. The engine requires an intake manifold designed for a tall-deck block, such as Chevrolet Performance manifold P/N 88961161. Conventional Big-Block intake manifolds can be used with spacers (not included).
NOTE: The engine can support fuel injection and also has a provision for a mechanical fuel pump (the production 8.0L camshaft does not have a fuel pump lobe).
