I know there will never be a manufacturer for these. To small demand. Sucks that there are so few power adders for olds motors. No supercharger kits. I would think someone would make one. I just saw an article in popular hot rodding that there making procharger brackets for amc motors. AMC before olds come on! i would think turbo headers would be the cheapest to make. I would make my own but i dont have the tools or time. I have some low compression engines that would love a turbo.
