The fuel system that Undy has looks more than over kill for the application. Better to be over kill than not enough. One thing you have to remember on these Cobras is that a lot of time the pick-up is the smallest place on the fuel system. A lot of the cars just have a 3/8 pick-up tube in the tank. This is something that I have talked with Kirkham about. Remember you will starve a single four much quicker than a 2X4 set up. You only have 2 bowls on a single 4 and 4 bowls on a dual 4 so you will drain the bowls down quicker on the same HP engine with the single 4V. I had a 2X4 set up on a Kirkham that made 750HP and ran the number 8 braided line to the front and went throught the manual fuel pump and used a stock log with it drilled out on the front for a #8 fitting. I had an electric fuel pump on the back feeding through the manual pump with the #6 pick-up and did not have any issues on the road course or drag strip. I think the fuel lines, log and the 4 bowls all helped this problem. Remember that you will drain the bowls on a 400HP single 4bl quicker than on a 700HP dual 4bl set up. I think you will be fine with what you are doing.
