I put a Mallory HyFire VI AL ignition box, 32 series billet, magnetic p/u distributor and recommended coil on my race car many years ago and it's worked great. Only a little trouble with one of the connectors. I haven't messed with it besides changing cap, rotor & Accel 8.8 plug wires periodically. This is their low deck BB version at Summit:

Mallory 32 series distributor for low deck Mopar BB.


As for carbs, I only know how to work on Holley's and their Ultra series work well for me, at the track at least. Staying just a little on the conservative side with CFM could help drivability & tunability.
