Third Time's A Charm

We wrap up the L&R Engines LS1 build and get it on the dyno

- Jim Smart

It can be safely said GM’s all-new LS1 opened the door to a new world of technology and performance in the 1990s. It can also be accurately stated the LS family is easily the most successful V-8 in American automotive history aside from the time-proven small-block Chevy, which remains in production 63 years later. We consider the LS engine something of a lesson in perfection—cathedral style intake ports, evenly spaced elliptical exhaust ports, fulcrum pivot rocker arms, a skirted cross-bolted block with a tall deck, steel crank, and a host of other great features. GM took all of the best attributes of the small-block Chevy and small-block Ford and rolled it all into the skirted LS. The LS has only gotten better with time and more advanced engineering, leading up to the LSX.
