Ice Ignition boxes have an adjustable timing curves. Not sure if there mapped every 1000rpm, but if they are i will follow what you gave me. Thanks and its just what i was looking for a few posts back. I curently use an MSD dist with a Ice magnetic box and the only fix i have found with the 3-4* lose at rpm is a crank trigger with locked out timing.
See if you can make it work. If not, just have your distributor curved Its probably cheaper anyways 😉
