I am setting up my MSD dizzy and wanted to make sure I am thinking correctly. It comes with the two heavy silver springs installed and the blue 21 degrees bushing installed.
I was going to change to the two light silver springs which will have my advance all in by what appears to be 2900 RPM's, according to what I can see on the MSD advance curve chart?
Then I was going to change to the Silver bushing for the advance stop, which is 25 degrees...
So about 9 degrees with the springs and 25 degrees with the advance stop ....all in at 34 degrees on my 10 to 1 compression BBF 460 @ 2900 RMPS?
