In 1992, GM brought to life a new-generation of small-block Chevy engine called the LT1. It displaced 5.7 L or 350 cu inches and was a conventional 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower cylinder temperatures and allowing the engine to run hotter using more compression than its earlier designs, thus producing more power. It soon became quite popular and a demand for new crate engines was building.
This was the same engine that came in the interceptor ”cop cars”. A surprisingly fast engine when you consider it came in many of the General motors luxury cars as well as the high performance cars.
For instance I have a 1995 Buick Raodmaster Touring Elite Wagon, it has a cop car LT1 engine in it, and let me say this, there is no doubt in my mind that this car will out run half of the so called ”muscle cars” made today. It has to have some serious and smooth power to propel a 5000 pound car to 80 MPH in a few seconds.
With almost 80,000 miles on my car, the engine has operated flawlessly, except for regular maintenance such as engine oil changes and staying on top of your cooling system and the related components and you have a long life powerful engine. Factory tune up intervals are 100,000 miles, which leaves little other than my maintenance suggestions to take care of.
My car still exceeds 21 MPG at 70 MPHish with the A/C and cruise control on. You can buy all sorts of LT1 engines that may never have been offered in a production car. Most of the non production engines were for factory racing teams and other special interests that promote the racing side of cars.
The LT4 was a special high-performance version of the new-generation LT1. It was introduced in the 1996 model year, for the last year of the C4 Corvette, and came standard on all manual transmission (ZF 6-speed equipped) C4 Corvettes. The engine was passed down to special versions of the Camaro and Firebird the next model year.
