Pro Flo 4 Timing
I’d say good alignment at 12 degrees but at 36 there is no alignment even though they claim “well within range” The width of the rotor tip ends up being the issue with the std Edelbrock phasing which is set up for perfect alignment at 12 degrees, the rotor they use on Chev Distributors looks like it’s more than twice the width (see below) The alignment that they’re achieving at 12 degrees would be more appropriate at say 24 degrees and then I’d say that it could be declared “well within range”
I’ll definitely be using an MSD adjustable rotor on mine.
