The plan is to see how they fit under an A body and then fab real ones one of these days. We plan to use flanges on both inlet and outlet bushings to make large tailpipes and headpipes easy to get on and off. Luckily, I have most of the real internals we need; just need to waterjet cut a couple of new end caps and the shell. They will be 2" longer versions of these (shown below) and they sound tougher then heck and flow like gangbusters and are relatively resonation free on the powerful Chevy-engined NOVA they are currently under.
