New MSD E-Curve Distributor install, review, and pics

4" from the block to the bottom of the cap (where cap and housing meet).

8 3/8" from the block to the tip of the male cap plug tower post.

That's exactly 1" taller than my MSD Billet dist. No wonder you have clearance issues. I bet it'd be a problem in mine too even though my car has the 2 spd. wiper motor. Thanks a bunch for the info.
