What is different about the MSD dist that it won't fit? I have been using a 440 dist in my 383 for 25 years and was thinking about upgrading to an MSD. now I'm confused....



I am going to use the taller RB distributor in a B (in this case 400) block to gain more clearance between the cap and passenger side valve cover. Hope that makes sense.



Thanks, I got that part, doing the same thing ( 440 dist in a 383 ) , I was confused about the msd not fitting in my old adapter . I am with the program now
