If you havent found it yet, here is the manual for the unit.

It's a pretty crude unit, the only sensor is a coolant temperature input (plus an optional oxygen sensor input). There is some limit to the horsepower rating, I think. The stock Chev TBI unit is more sophisticated but I dont know how well the Chev unit would do in a stationary application (usually stationary apps run constant rpm). There is also the Chev marine TBI that you see on egay sometimes. All would probably be better than a carb anyway.... is cost a factor?

A better solution is the Edelbrock TBI...there is one on egay (item 290135644662). These units have a MAP sensor and an air temp sensor so they would be much more flexible. The price is higher though. It uses a GM controller.
