Don’t sell yourself short, we have plenty of Remanufactured Chevy 5.7 liter engines for sale.
Over the years savvy car buyers have consistently put their money in a 5.7 liter Chevy engine because it has evolved into an engine superstar. The first LT1 engine sold was in the 1992 Corvette. This LT1 engine had aluminum heads and a cast iron block. Early LT1 engines had 4 x 3.48 inch bore and stroke, and the control modular was a small computer, which controlled key engine parameters.
In 1994 a new version of the LT1 went up for sale. This 5.7 litre engine had a powertrain control modular, which managed the transmission as well as the engine. The powertrain modular gave these drivetrain components more unity in action. Chevy also added a second catalytic converter and additional oxygen sensor in 1996, which gave the engine more power efficiency.
Advancements in the 5.7 litre were considered super sized in the engine business so by 1997 the Corvette had moved on to an advanced generation engine design. The Camaro was the only car left in the Chevy lineup that featured the powerful LT1.
All LT1 engines had 16 values and eight cylinders, which were activated by the push-rod system. That gave the engine a compression ratio of 10.4:1. The 1992 granddaddy engine had 300 horsepower and 330ft-lbs of torque, but when it was featured in the Camaro from 1993 to 1995 it had 275 horsepower and 325 ft-lbs of torque. That engine was updated to 285 horsepower and 335ft-lbs of torque in 1996.
In 1997 the LS1 5.7 liter engine made its debut in the Corvette. It was a lighter and much more durable engine thanks to its aluminum construction. The bore and stroke on the LS1 were 3.9 x 3.62 inches, and the new architectural design positioned the fuel injectors near the intake valves, which gave the engine a great mixture of fuel and air. That marriage resulted in better control of the combustion process. The 345 horsepower 330ft-lbs of torque LS1 5.7 liter engine was used in Corvettes until the more powerful LS2 was introduced in 2005.
