The only thing that isn't original to the 98 is the basic engine including harmonic balancer and flex plate. We put the 98 intake, throttle body, injectors, distributor, etc. onto the 95 engine. Intake and right exhaust manifold from the 98 were installed on the 95 engine because the 95 engine had EGR and the 98 didn't.
All wiring, sensors, injectors, etc. are original to the 98.
I don't know how it ran before because the original engine had a connecting rod through the oil pan....so, no telling how it ran.
We had a guy scan it...don't remember the codes, but there were two. One was coolant temp. or something, and the other said no cam sensor signal. We installed a new cam sensor in the distributor, and it runs the same.
Rotor is pointing at the mark when #1 cyl. is at TDC.
I put a 98 Engine in a 95 before, and we just put a 2000 engine in a 94, and had NO problems...just changed intakes, etc. just like we did this time!
As far as the flex plate....that should have nothing to do with it? Basically, we have an unweighted torque converter and unweighted (95) flex plate....so, that should only just cause vibration...correct?
thanks for the help and advice!

So ECT (Engine Coolant Temp) is a code. The quick and dirty deal is to plug in a resistor across the connector terminals so you can rule that out. The computer does monitor this so it can see how quickly it comes up to temp. There are codes for this, but at least you can plug in a 90 degree resistance and see if it's still super fat. From THIS PAGE it looks like a 5k ohm resistor will do it. Clear the codes after checking. If the connector is disconnected, it will be no retun and 'see' very cold and force it rich. Check those wires!

I thought the difference between the early and late Magnum flexplates was the early plate had an asymmetricical converter bolt pattern, and the late plate had a symmetrical bolt pattern

Have you checked your distibutor/ crank sensor sync? You will need a scan tool to do this properly. You can get it close by putting the engine on TDC and removing the dist. cap and aligning the rotor with the mark on the distributor.
