If that is the cam that you actually got in this motor,then the locked timing will actually improve the fuel mileage.
You want to eliminate the centrifical advance but retain and still use the vacuum advance system
(ported vacuum) There is nothing wrong with the 750cfm carb. Get a fuel filter.
The cam is a bad choice for your truck.

You do not need a timing tape. as 36deg is 1/10th the circumfrence of the balancer, from TDC.
mark the balancer for 36deg BTDC.

Set the timng of the now locked distributor to 36deg BTDC with the va c advance disconnected from the carb.
Then connect the vac advance to the ported vac source, on the carb.
If/when it is hard to start when hot use a spark interupt switch.

If you get a different cam you will need a different setup.
The builder owes you a cam and lifter set that is suitable with a stock 2200stall.
Keep the .050" duration less than 218.

Change gthe cam not the torque converter. Its a truck not a race car.
Change the intake too.
