Carl,
Just speaking for me...
Speed demon, Holly, Q-jet, and especially Edelbrock, You might as well put a garbage can on top of the engine ! all they are good for is BURNING gas, Go ahead and go with the TBI It's not as hard as your think it is, Ive installed TBI on both of my trucks. No problems ever ! There's also a electric Trans torque lock up plug on the side of the newer 700R that's controlled by the ECM but Ive seen a few companies that offer a kit for that as well...

Just make sure you got the TV cable adjusted right as everyone has said
Good luck and keep us posted
Todd
