I was able to find the original distributor in storage, so i am going to install that asap, to rule out the MSD that is currently firing the motor.
I purchased the MSD "ready to run" distributor through HotHeads, as well as all the other ingredients to put this motor together, then a very reputable shop did the assembly. Old school racers, who have done hemis.
I have heard much heresay that the msd s are often culprit, (find this hard to believe,) so just to rule it out, going to try the O.E. dist.
btw , this motor really runs pretty nice, but i know there is untapped power on hand once this trouble is sorted.
Thanks for the replies. I will do update asap. Russ
