Thanks for the advice. I have decided to go crank trigger after all. I have made a Ø180 x 5mm thick 60-2 trigger wheel and mounted it to the front of the crank. What position sensor would you recommend? Hall or magnetic? Any particular sensor? I'd prefer something I can purchase through Repco, BNT or Supercheap. Dave

I plan to convert my gen1 SBC to LS style coils. The vehicle is 50/50 drag race and street, data logging would be useful including my AEM wideband AFR. I'm thinking Atom and wasted spark. The real question is how to trigger the ECU? I think the TPI chevs had a distributor with two triggers, is that the way to go? Trying to avoid a crank trigger if I can. Anything else i should be aware of? Dave
