I have discovered my problem well the rpm one anyway
checked out the runout thing I had with the harmonic
looks like the crank is either bent or the bearings are shot ... it is not spinning central
it is making loops if you get my drift.
So it is a new crank or at the very least a full set of main bearings.
My oil pressure is good though so not sure what is going on there but something is screwy ?
Know where I can get another 4g64 7bolt crank?
