The trick would be finding Jag (or similar-sized S-U) carbs that aren't either worn out or priced higher than the reproductive system on a giraffe! Making the manifold(s) is just a matter of milling and TIG welding something appropriate to adapt the carbs to the cylinder head.

Another "trick" might be dialing the S.U. carbs to the Stovebolt engine. Haven't played with S.U.'s for years, so not aware of tuning parts currently available. But they offered many different needle profiles.
