(Measured from mounting surface to end of distributor shaft) Powerflite Posted 2016-08-01 8:54 PM (#518180 - in reply to #518139) Subject: RE: Distributor Shaft Lengths Expert 5K+ Posts: 9700 Location: So. Cal Yes, they all have the same length distributor shaft. I pulled the distributor from the 315 in my truck and compared to the 331 hemi in my Savoy.
