Got the Zenith installed...man what a difference. Runs like a champ. Lost just a little punch above half throttle but not surprised going from a venturi that was badly undersized. The low to mid throttle response, smooth running, and much better fuel economy was well worth the little loss above. May do a little tuning on it just to see if that makes a difference. As a side note, if any of you are trying to locate cup grease, or the closest equivalent that exists today (lithium soap/mineral oil) for your distributors, speedo drive, etc...I found this. Can be ordered off Amazon and other places. See pic. Also got the alignment and gear box adjustment done...drives absolutely straight with zero wandering. It's a pleasure to drive now. I'm going to say I'm pretty much done with it as is. Itll be a little while before I have a chance to get the 302 done for it but I'm in no hurry.
