So to correctly time my 360 magnum i will need to leave the initial timing at 8 degrees then slowly rev up while shining the light on the balancer and keep reving up untill the distributer stops advancing and set it to 35 degrees at the rpm where it stops advancing correct? then i add the initial timing timing to the mechanical advance to get my totoal timing and if i want to change the mechanical advance i will need to get a spring kit for my distributer correct?
