looking for the right intake for my 426 stroker

My father has the Kendig carb. The predecessor to the predator. It was a half baked idea. A ramp inside with a tube and an adjustable collar on the end of the tube. Open the throttle and the tube swings along the ramp. The farther along the ramp the farther the tube gets from the ramp the more fuel is allowed to enter the tube. Half baked.
