Well this is EFI and a dual sync distributor so it cost about $400.00 to switch it out. I will spend the $$ but I don't want to spend $$ chasing down a maybe solution, this is where patients comes to play which I normally have none of.
Yes we did a spark plug wire change and went thru 3 sets of plugs chasing it... Everything is new on this set up so I am leaning toward the dual sync that is the problem cause I bought it used.
If it is the distributor, I may go to a lean burn distributor and grind off 7 of the teeth on the wheel and use it for the cam signal and then buy a separate dedicated crank trigger and throw the Fast Distributer in the trash.
