8.0L V-8 LFI Features
& Specifications
When it comes to pulling your car hauler or offshore racing boat, the heavy-duty 8.0L Big-Block does it without breaking a sweat. It's designed for CNG on-highway applications and because it's a Big-Block, it delivers strong, low-rpm torque.
A tall-deck version of the latest block casting, featuring full-length water jackets, thicker main 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" stroke helps maximize torque. It also features a crank-triggered ignition system, with 4x camshaft and 58x crankshaft reluctor wheels.
