Several years ago and before the eyes stated to tank on me I got a billet dual plug hemi chambered OHC 302 GMC head about 60% done. No water jacket so was a dragster only unit. At that time I was looking at side draft Mikuni's but Jon advised that when new the Mikuni was low priced, easy to tune, and ran well but longevity wasn't a strong point. Since they are low priced maybe using three for development could be a possibility and then upgrade to something better. Without a dyno I would NEVER tangle with Webers again. Man I hope your project once started comes to fruition.
