Duraspark Starting Point

[331cougar]

Im looking for a starting point on setting up the distributor.

331CID, 10.16:1 CR, ProComp Alum. Heads, CompCams 35-238-3 has 262 duration.


Im thinking 12 on initial timing and 36 total advance?

Hi! sound pretty good, 12 initial and 34-36 total. did you change anything inside the dizzy. you can recuve it by changing how much mechanical advance get. 20 degree mechanical and you want it to come around 2500 RPM by changing the spring.
