i have Bosch platinum iridium plugs that are supposed to be a bright bluish white. I have used these before in multiple 350 Vortec powered trucks, and previous Cadillac lowrider (with 8.2L 500ci). currently have the Cad 472 in my '80. HEI is from a 75 500 with all new guts. Battery cables are welding cables. What would make it have such a weak spark?
