Keith, have you done a test with Ricks billet distributor (not the one with ignition module) compared to an MSD Pro Billet? I bought one of these from Bob George over the winter and ran it on the dyno in my new 540. We locked out the timing and used the engine shop's MSD 6-al and my MSD HVC coil. I am quite pleased with the results but did not have another distributor to compare it to.
