   I'll check with the guy that built it this week . It's possible that
the rebuilt converter he supplied doesn't have lockup , I understand
that some don't but that may be an aftermarket thing

A torque converter is like one fan blowing on another fan to transfer rotation while allowing slippage without wear, though it wastes energy as heat. The lockup is a clutch that connects the two fans (turbines) together when conditions allow. The indication of lockup is the tach needle moving in sync with the speedo needle instead of jumping when you change gas pedal pressure.

In Drive with the brakes locked full throttle engine RPM should be around 2000 unless you have the actual specs.
Torque converters developed the simpler fluid couplings of the late 1930's and were highly improved for WW2 airplane engine superchargers, to isolate crankshaft power stroke vibrations from the high flywheel inertia of the compressor rotor.
