I have a magnum 318 based stoker in the duster, it has a M1 with injection ports, but I’m running a blowthru carb for now. I wanted one for my 360 magnum engine build for the truck. Turbo’s like a single plane. It’s hard to find a single plane for a magnum head that is a bolt on. I’m sure I could mod an LA one to work, and I may have to. I found some on ebay for 600-1000$.
