Default Re: crab distributor on a 38 24 stud

Im with Kube. The three bolt 11a helmet distributor has the exact same advance curve as the 21a crab and performs the exact same and in my opinion given the distance between the bushings and the fact the rotor is in the middle of the shaft rather than attached to the end, I much prefer the helmet distributor as the bushings last longer in them over the crab.

But I can understand plug wire changes are much easier on a crab type as well as the cap and rotor.
