Very nice work as usual. Did you end up buying the Novac kit? They probably have the most complete kit. I bet your synchros looked ok. I have yet to find a really worn one and Ive been through about a dozen Sm rebuilds. They are quite fun to do.

You might find that the 13.2 cruise A/F will be fine. I have a wideband and have done much carb and fuel injector tuning in the past. Striving for the stoichiometric mixture for a gasoline carb engine can be challenge, and found that lean surges will rear its ugly head. I attribute this to the differences in runner intake manifolding. I'm assuming you have one oygen sensor gathering the average of at least one bank if not the entire exhaust?? With that big monster engine, if it is running good at 13.2 I might be happy with that, but I fully understand the need to tinker for sure.

Keep up the good work, enjoy your write ups.
