Need to upgrade optispark on my supercharged 383 LT1 in 97 TA. spark getting blown away at 5600 rpm. Considering LTCC or Delteq coil on plug systems. anyone got any experience or know of any other options? Thanx, Brian

Best option here is to go with the MSD Opti spark. all new parts and built to work, also has a mechanical advance setting for specials.
