Can somebody tell me what i should use for my ignition system. I am in the process of going single so i need to upgrade my ignition and i wanted to use crane amps and coils. I was told to get the HI-6 amp and LX-92 coils. my question is do i need two amps, one for each leading plug and just run the stock setup for the trailing plugs or one amp powering the two leading LX-92 coils. Which of these setups is correct if either and is stock trailing setup ok? Garfinkle is helping me on the install and he is unsure also. I am running a Power FC, A/I 70/30 mixture and looking for 450whp, if this helps.
