Check Out this video about one of our customers, Skuli Skulason and his son's 1968 Camaro LS3 Conversion project. It was done in four months, after two years of planning. All the work was done by the father/son team with a help from few friends who wanted to be a part of the project. Southern Performance Systems supplied all of the parts and "Did a hell of a job in a relatively short notice and backed us up 100%." Skuli and his son live in Iceland, a long way from US and needed a supplier that was reliable. On top of the Turnkey Engine Package, SPS also supplied the suspension, steering, brakes, cooling, fuel system and dash gauges. The car is amazing and drives like a modern sports car with a real muscle ingredients.

Southern Performance Systems was founded in 1994. Located in Sugar Hill, Georgia outside of Atlanta, Southern Performance Systems specializes in providing the most complete "Turn-Key" LS engine packages for classic cars, muscle cars and trucks. In addition to engine packages to make a LS conversion complete we offer upgrades for brakes, suspensions, rear ends, air conditioning, electronic gauges, radiators and headers. Years of being an install center, doing design work and testing have made us a leader in the LS conversion market.
