I can be done and yes the motor did get great mileage in the F-body cars, but you must consider that the F-body is quite a bit lighter than the truck, and most importantly the aerodynamics are FAR better than the truck will ever be.

That said, it's going to be a lot of trouble for a result that feels underpowered and doesn't get that great of fuel economy.

Instead, look into a TBI 305 or 350 with a 700R4.
