dash wiring ?
behind and pluged into the dash there is a round metal thing just to the upper left of the clutch res. what is it

710k 1974

Norcal, if you mean a round thing about 2" diameter, it's the ignition ballast resistor. Circuitwise, it's placed is series with the ignition coil to lower the voltage to about 16V (if I remember).
The ballast is shorted out when starter button is pressed to give more kick to the coil and have more powerful sparks; it is put in series when starter button is released.

It's likely the flasher relay or the ballast resistor. To verify, check for a wiring schematic on the top of the relay case. If no schematic, but instead a thumb screw then you are looking at the ballast resistor. It's kinda hard to judge by your placement description. And by description it sounds nothing like the rpm mod.

My best discription of these comonents:
Ballast resistor: Looks like a "bicycle bell" with a knurled thumbscrew in the middle.
Flasher relay: taller than it is arouund, sits vertically on a bracket off the body panel.
4500 rpm module: black plastic box somewhat larger than a deck of cards (about 1" larger in all dimensions).
Most of these things are to the RIGHT of the clutch resevoir (and above it); you may be describing the small "cigarette lighter socket" by the four way flasher button. This socket is an auxillary power outlet.
