Tom, years ago I mildly hopped up a 196 in a 62 American convertible. I replaced the intake plate with one I fabricated to take 2 MG SU carbs. They were mounted to 90 degree elbows welded to the plate. Ran OK but I think the stock 2 bbl intake from the 138 horse engine ran as good. Offy used to make a manifold that used 2 stock 1 bbl carbs. This engine did respond well to a 2 inch exh pipe and free flowing muffler. I also had a flathead with a 55 statesman 2 carb aluminum high comp. head. Not really worth the effort but looked neat. Swapping in a 232/258 into a 196 car is a hassle. Did it in a 65 American. Had 2 of them . One came with the 232 the other had the 196. Quite a difference in Radiator location and motor mounts. I swapped a 401 into one easier than a 232. I would think a 196 with a turbo is the way to go. Forged crank and rods stock. Piston walls very thick. Could handle lots of boost and probably stay together. Mike
