The LT5 is not forgotten

[ZRapid-1]

Good to see the LT5 recognized as one of the best engines. Made it into the super Vette ZR-1!

LT5; 5.7-liter V-8, 375 hp
The LT5 went under the hood of the first Corvette ZR-1 in 1989 but wasn't made in-house. GM contracted development of the engine to Lotus Engineering (which was actually owned by GM at that time). Originally, Lotus designed a clean-sheet design for the LT5 that was intended to make 400 hp. However, GM wanted to use the engine block from the existing small-block V-8, and the Lotus modified its design to meet GM's requirements. The consequence was that the power output for the engine dropped to 375 hp. The new engine also ended up with both a longer stroke and a smaller bore than the old V-8. Production of the LT5 was contracted out to Mercury Marine.
Why is it one of the best? The LT5 was all-new engine that veered from the small-block norm, it was truly a global collaboration that helped to produce this super Vette.
