Hello, I'm in the process of building myself a cast iron dual stock carb intake for the Ford 226 flathead. The intake will be based on the NICSON design but not copied because I'm building it from the ground up from a stock intake. The intake will not have the heat riser area. Many will may say build it in aluminum but I have first hand access to a cast iron foundry. My question is: would there be a market to sell some of these hard to find intakes?
