![]() The LS3 was produced for the '08-'13 Corvette and Corvette Grand Sport (although it was a modified version with dry sump oil cooling and a unique forged steel crankshaft). The old T56 transmission was dropped in favor of a TR6060, which provided improved shift links and helped power the C6 to a 0-60 mph time in just over 4.0 seconds (which was faster than any production Corvette made up to that time). The 6.2 L V8 was a serious upgrade for the Corvette (C6), producing 430 hp and 424 lb/ft of torque. The LS3 debuted in 2008 as a part of GM’s Generation IV engines. In 2001, the engine was tweaked for a small bump in power (to 350 hp), but the engine was a radical departure from V8 engines of the past and set General Motors on the path to building better LS engines with increasingly more power. The multi-port injection allowed the engine to be tuned more precisely than predecessors, resulting in better efficiency and fuel economy while producing better thrust during higher rpms. The LS1 had significant changes because it used electronic ignition, using a modified ECU to control firing rather than old-fashioned distributor caps. It also made an appearance in the ‘04 Pontiac GTO. It wasn’t long before the new Gen III engine found its way into other vehicles like the ‘98 - 2002 Pontiac TransAm, Firebird, Chevy Camaro Z28, and SS models. The new hydroformed frame improved the structural stability of the car, and while the engine produced only 345 hp when it was paired with the new Borg Warner T56 six=speed manual, the new Corvette pushed a 4.5 second 0 - 60 and redlined at 175 mph at its top speed. When it was first released as a 5.7 L V8, GM needed a new engine for the new fifth generation of the Corvette. The weight reduction was significant, providing increased strength and power for the powerplant and a way to faster times on the track. As the first V8 to use an all-aluminum block, the engine was designed to weigh nearly 88 pounds less than its predecessor. When GM introduced the LS engine for the 1997 Corvette, they knew they were working in new territory. But first, a little bit of history might be in order. What is the difference between the LS1 and the LS3 engines? Which is the better engine? If you aren’t already familiar with these two excellent engines, let’s take a moment to examine them. The Gen 3 small block debuted as a 5.7 L V8 for the 1997 Corvette, but in 2008, GM perfected the small block to release the LS3 (Gen IV engines) with a significant bump in both power and performance. While plenty of V8 engines were made during the last hundred and twenty years of automotive history, the LS family of Chevy small blocks is consistently rated as one of the best. It produced 430 hp and 424 lb/ft of torque.Įvery classic car lover knows that the V8 engine is the only way to go if you want real power for a rebuild. The LS3 was a 6.2L V8 (fourth generation) produced for the ‘08 Corvette. The LS1 engine was a 5.7 V8 with 345 hp and 350 lb/ft of torque. ![]() The LS family of V8 engines, which GM labeled as the Generation III Small Block, debuted in 1997. But what is the difference between LS1 vs LS3? Let’s take a look at each. ![]() If you are a Chevy lover, you probably know about the LS engine family. ![]()
