As a hot rodder from the 80s and 90s, I built EFI systems.....,really expensive early systems..... Only to have less peak power and the same economy as a properly tuned carb. After rebuilding the same motors for the third time and getting them retuned.....for the 7th time.... I realized EFI has its limitations.
Drive enough miles and one gets disenchanted with vehicle and boat OEMs
With that stated.... Anyone have a cam-driven mag with mechanical advance I can use on an LS with an 8.5" diameter damper
