that distributor uses the MSD rotor from above...or vice a versa...

that one has 22 or 24 degrees of initial advance with 34 degrees at 3000 rpm.....I am having problems with spark scatter with the msd or pc 2015 with it.....no spark scatter with MP chrome box...but spark is no where the same as the 6al or 2015....

I working covering up part of the rotor with heat shrink tubing...but have not gotten chance to get it back in the car yet.....car is up in the air..
