Chevrolet small-block engine
In 1992, GM created a new-generation small-block engine called the "LT1 350", not to be confused with the high-output Generation I LT-1 of the 1970s. It displaced , and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and allowing the engine to run at a higher compression than its immediate predecessors.
Small engine repair
Small engine repair is a vocational occupation that involves the maintenance and repair of small engines: low-power internal combustion engines (gasoline/petrol) or electric engines. Equipment repaired includes chain saws, string trimmers, leaf blowers, snow blowers, lawn mowers, wood chippers, go-karts and sometimes more powerful engines used in outboard motors, snowmobiles, and motorcycles. While often touted as a separate job by commercial vocational schools, it may also be a skill someone uses as part of a larger job, such as rancher or park ranger.
