The bad thing about the electric wiper conversion is there is no provision for the wiper co-ordinator if you have the WS washer or for the electric switch to neatly mount in the dash. The electric is also somewhat limited in speed and function as compared to the vacuum motor.

To use the original switch with cable setup and the co-ordinator you need to make some kind of adapter to replace the electric switch that comes with the motor with something the cable and co-ordinator can operate. Using the original dash hole with the new electric switch is no issue but using the bezel leaves an unsightly gap under the knob because of the sweep control lever on the original wiper switch. To cover the gap in the bezel the sweep lever needs to be cut and part of it replaced on the switch shaft to hide the gap. Once cut the lever is destroyed for farther use if you or a future owner wanted to go back to the original vacuum setup some day.

You can get the vacuum motor rebuilt for less than half the money the electric setup costs and the T Bird dual action fuel pump is not terribly expensive either. That pump will fit and work only requiring a bit of extra tubing to connect. I went the electric route with switch adapter to stay with the original switch and co-ordinator but in hindsight I do not think it was worth the effort and have seriously considered reinstalling the vacuum motor with a new fuel pump.

On the engine issue, Did you turn it over freely 6 revolutions and then it stopped or was it 6 times with only a few degrees each time until it reached a certain spot and stopped?

If it turned completely thru several revolutions then I would look for maybe some kind of liquid that filled a cylinder and has hydro blocked a piston but if only a few degrees each time before it stopped then it could be a piston or stuck valves.

I ran into stuck valves on a long sitting V8 which were so completely frozen several push rods were bent with my continued trying . For the hydro block you could remove the plugs and try again and if there is still a problem at a certain point then most likely valves and it would be good to quit the lower end and address the valve side.
