best racing ign system.

63 dart dirt track circle track stock car. 360 2bbl. race duration is ~30 minutes. 6200 RPM limiter. I have a recurved OE electronic dist. what module & coil would you guys recommend? I can use a regular flat 4 pin module or an HEI module that mounts under the dist. I think I can get by with an externally mounted Ecoil or if not then a regular round coil. thank you for your time. I want the best!. RR
