One advantage of Hotrods system: Mechanical Advance is accounted for. I have often wondered how much the mechanical advance changed over the years. I have several Distributors from several salvage operations. All will fit. All will work. And other than the height of the cap they all run just fine. In my humble opinion..it just does not matter a lot with the stock 235. It would seem to be happy with a wide range of tuning. Makes sense, it was a "work" engine. Not a performance beast. Perhaps a 261 might be a little fussy? IDK. The last 216 I worked on ran fine with both early and late distributors so it was not fussy either. More issues from carb and oil to the rockers than from the dizzy.
