[GH85Carrera]

The GM LT5 engine was originally designed and built for the 1990 Chevy Corvette ZR-1. It was designed however jointly with Lotus and actually built by Mercury Marine in Stillwater, Oklahoma. Reason being, GM had little experience building all aluminum engines at the time. The LT5 produced 380 horsepower through a 5.7L, 32-valve, small block V8. Lightweight pistons and connecting rods, a forged crankshaft and 11:1 compression ratio took the ZR-1 to 60mph in 4.5 seconds with a top speed of 175mph
