Yes, but why couldn't you use the stock Mopar pickup?

From what I gather it is "semi" batch fire. 3 sets of 2 cyls. I have a lot more reading to do. I'll get into this on my build thread, and try to stop hijacking rusty's thread.

Naw man it's fine. Ain't it about a slant 6? We're good.

Not sure, I forgot the reason why MadDart rigged it up this way when he was building this car, I went with the Jeep cam sensor too with an adaptor from SD concepts.

The Mopar two wire magnetic pickup, as reliable as it is, doesn't play well with computers. Many many people have issues getting a reliable, readable signal for the computer. The Jeep CPS and many others are a three wire hall effect sensor. The computer sees the signal from the hall effect as either on or off, high or low, voltage output or no voltage output. The Mopar magnetic pickup outputs a sine wave amplitude that usually varies too much for the computer.

Thanks for that info, but then why are most crank triggers (aftermarket) 2 wire reluctance sensors?

I'm not an engineer, but you can search the Internet and find issue after issue the the Mopar magnetic pickup and not with the Ford Duraspark or GM HEI pickups when used with EFI systems. I recall something about the amplitude variation or the small cap letting spark disrupt the signal. It's not a two wire magnetic pickup thing it's a Mopar Electronic Ignition distributor and EFI compatibility thing.
