Pontiac Solstice Forum - View Single Post - 5.3L Small Block V8 Engine (from Impala SS)

LS4

5.3 L LS4 V8 in a 2006 Chevrolet Impala SS.The LS4 is a smaller 5.3 L (325 in³) version of the Generation IV block. Though it has the same displacement as the Vortec 5300 LH6, it differs in that it has an aluminum block rather than an iron one and it uses the same cylinder head as the Generation III LS6 engine.

A version of this engine is adapted for transverse front-wheel drive application. In order to fit into the smaller engine compartments designed for V-6s, in the front-wheel drive Pontiac Grand Prix GXP, for instance, the LS4 engine block had to be shortened by one inch. Displacement on Demand is also used. Output of this version is 303 hp (226 kW) and 323 ft·lbf (438 N·m).

Applications:

2006 Chevrolet Impala/Monte Carlo SS
2006 Pontiac Grand Prix GXP

BTW: The Impalla SS tips the scales at a hefty 3,712 pounds
And it does 0-60 in 5.7 seconds! And thats front-wheel drive.
