| PROFORM HEI distributors put spark, coil, and module in one self-contained unit with simple one-wire hookup. Applications cover small block and big block Chevrolet, Ford 302 and 351W, and Chrysler 273 through 360, with melonized steel gears for compatibility with most cam cores. Street models carry adjustable vacuum advance to dial in part-throttle timing; race versions come with the vacuum advance locked out. Caps, rotors, coils, and rebuild components are all available separately to keep any HEI in service. |
