what racing ign do you recommend?

circle track 1/3 third mile dirt. 360 9-1 2bbl. No ign "boxes", MSD I would think they are referring to. max RPM maybe 6000. what ign system (box/ballast/coil) would you recommend? I have OE electronic dist. I have OE 70's HEI module & "standard motor products" HEI module at the moment along with the straight thru no ballast furd module with the squarish wrap around steel. I kinda like the FBO mopar module with the built in RPM limiter tho tech might have a problem with it. what do you guys think? & thank you for your time. RR
