Anyone know if low oil pressure will shut the motor down at high RPM? And cause bucking.

No and in all likelyhood not likely to cause a "bucking".

How high rpm is "high"? Usually high rpm bucking is caused by plugs and/or plug wires.

It's starting around 3800 and really get bad as it builds.
And check gauge light comes on and looks like oil pressure is dropping.

I can email you a dyno chart if you think that may help..

on the dyno it fall at 4300 rpm

I had to make a bracket for the crank sensor because I put the 94 motor in and kept my 90 wiring & computer..
So I don't know if this could be my problem let me know what you think .
