IMO, I would do the stand-a-lone. Little costly, but at least you don't have to deal with the headache if you aren't good at wiring. I would seriously recommend machining a hole in the back of the intake and dropping a distributor. If you use a regular HEI, I would drop a MSD module in it. Or just get a MSD distributor with highout put. Of course that means getting a new balancer with the timing marks and a opti delete plate. Vent or no vent on the opti, it will fail much sooner than HEI. Plus, it is just a PITA to change out. I have changed way too many out for people. Makes for getting a good deal on a LT1 car though when the person can't figure out why the car doesn't start.

Run long tube headers that are recommended for the truck. The oval port headers work just fine on the D-Port heads. I tried block huggers at first. Passenger side hits on the cross member.

If I ever find a donor car for cheap, I will probably switch it over to fuel injection and put the T-56 in the truck.

Lots of choice's, ready to see your build thread.
