DIY LTCC or similar system for LT1s

I'd pay about $25 for 8 from the junkyard assuming they'd work with the LT1 PCM. It's loaded with LS engines these days.

Sure, the LS coils are simple and the LS controls do dwell, but so what? The LT1 PCM isn't a LS PCM. I don't believe the LT1 ignition module is as basic. I have no idea if a LT1 PCM does any internal dwell timing or not but I doubt it. I expect the LT1 ignition module is a current limiting HEI type design. So, if you run the LT1/TBI etc coil on straight switched power you'll likely just burn it out.
