MSD distributor 408 stroker

I disagree. An 1/8 is a lot in some worlds. This could be one of them. The intermediate shaft could also have been a bit short. Everything adds up.

OP, S-K Speed on Long Island, New York?
Yes, BTW...thanks to all y’all chiming in. Motor was running fine since I picked up car but was losing power and acting logy lately. Then it wouldn’t fire at all, pretty much determined it was MSD box failing and then dying-thus the slowing and sluggish deal. My muscle car mechanic said they see this periodically. Anyway, I will check new distributor for shims, that would be awesome if I can take care of it and get this bizatch Dart back on the road! Hambony.
