The LT1 was a huge stepping stone for GM’s late model performance. The Lt1 made it’s first appearance in the early 1970s in Corvettes and Camaros. The 2nd generation engines were produced from 1992-1997. You can find versions of these engines in the Caprice, Roadmaster, F-Bodies, Fleetwood, Impala SS, and the Corvette. The LT1 is a 350ci small block V8. Overall this motor has a reputation for good performance and dependability.
