I dont think my old man even touched the distributer, i think he just bolted the mopar distributer that came with the crate engine in and dialed in the total timing and let the initial fall wherever it fell.
That being said the magnum engines require 32 degrees total timing, if i run 91 octane fuel could i bump it up to 36 degrees? the compression ratio is not low but not extremley high ether its 9 to 5 to 1. And i will take my distributer out soon and get the slots shortened to around 20 degrees mechanical advance so i can run 12 to 15 degrees of initial timing.Oh and my mechanical advance is all in at about 2500 rpm.
