Not sure about the dual side draft carbs. The intake looks like a nice piece and they are costly to replace on these babies! I know as a marine engine it would be designed to run pretty much half to full throttle constantly, so this seems like a good combination for the strip for higher operating range. Any input? Has anyone else run this setup in a hot street car or drag application? Looks like it could be an awesome intake for turbocharged application! Don't have the money for that right now...lol.
