Swap LS Engines into Chevelles and GM A-Bodies : 1964-1972

The GM LS engine is a popular choice for swapping into classic cars due to its combination of horsepower, torque, and compact design. These modern pushrod V-8s can be installed in vintage GM muscle cars, including Chevelles and other A-Body models, with relative ease. General Motors produced around 500.000 Chevelles and A-Body cars between 1968 and 1970.

Jefferson Bryant, experienced in LS swaps, provides a detailed guide for installing an LS engine into a Chevelle, Buick GS, Oldsmobile Cutlass, or Pontiac GTO.

The process requires selecting or fabricating motor mounts and adapter plates, integrating electronic engine controls and wiring, and, for fuel-injected systems, installing a compatible fuel tank, high-pressure pump, fuel lines, and related components.

Bryant covers all critical steps, offering time-saving techniques and solutions to common problems. The guide also includes instructions for performing an LT engine swap into an A-Body car.
