New 440 installed with an Alterkation
It was the guy that you were replying to who my reply should have been directed at.
I'm sure a power rack can be used instead of a manual rack. Carb and hood clearance would be the same as a stock K I imagine since you still use the stock trans mount location and the engine wants to be in the stock location , though it could be a tad lower because of the potential added ground clearance , BUT the headers still hang as low unless one were to get a custom set of headers made considering the extra space with the steering box and the torsion bars out of the picture.
