Sweeet! Back in the day I had thoughts of the 3 X Weber setup, but the cost and space issue held me back. It didnt appear to me that the carbs/manifold would clear the power brake booster. I also had wondered about an OHC head on a 292, or a 292 crank in a cammer block. You are living my dreams of 1984, man!! What are spin tech mufflers? I would agree that 2 in glasspacks are probably not SOTA when it comes to flow.
