what do you mean it runs good but loss of power.... some sort of marks on the dizzy are going to happen from everything ive seen, the spark plugs however could be an issue. in the back of a Haynes manual for the mustang there is a page of different spark plug states...may be your best bet as you have one to compare to.

We'll I mean it's not crapping out and there are no check engine codes just loss of power but I notice a whisling sound as the Rpms increase

All cylinders are firing and all compression is good

OP, what are these points you write about?

i assumed it was the electrical pickups on the underside of the distributer cap

was this an issue that just started one day? did you disassemble and put it back together then notice the issue?
