MP Distributor Tuning Tutorial
great info. I was fighting to get 35 degrees total for my Hemi and still have it start. Been stuck @33 total. Ordered the spring kit which now has a Summit part number #SUM 850535. The Mallory kit has been discontinued.
weather warming up...can't wait to add the extra / needed 2 degrees of total. I kept the compression reasonable for the street (10.5 to 1) to be able to give it timing without detonation on pump gas....(JMHO) without timing they are all noise/ no power.
