Thanks for the replies, Think I'm going to be swapping over to a set of SU Carbs I refreshed, so while I'm at it I'll have to spend a day checking out wear on my ignition components.
It does it every time I go WOT no matter downhill or uphill, it has never done it in the lower rpms; always around 5,500. I notice the other day some wires over by the main relay area were extremely brittle, the two blue wires that connect near the battery....I'm going to start there and work my way to the distributor/coil. I do have a MSD Blaster 2 coil that I forgot to mention but everything else is factory.....
