7.3 is a viable way to go. Budget constraints will put the Kabash on the project because the expense of the adaptation has gone sky high. Valving on these things was and is very restrictive. Open them up and utilize the stock manifold with whatever carb is selected. This alone will bring life to the motor. Want a bit more useable punch? Turbo! He has a good exhaust system that will work. These things were designed primarily to work at 1500 rpm's all day long, and were put into service in big dump trucks to move big loads of dirt around job sites at low rpm. Get it to breathe, and even with the stock camshaft, it will come alive.

its amazing how much you can do just with a little bit of basic machine work, that most decent shops can pull off, will do to a motor of that size..... mild porting and a better carb alone would make her a little more happy, if your budget is large enough you could even go for custom pistons to bump up compression a little and a custom cam grind..... but you definately wont find any off the shelf products that'll accomplish that for you.... a turbo definately would be an inexpensive way to add quite a bit of power as well.....
