  1. I think (whatever that's worth) that you have the right idea.  I would use 12's long block and dress it with the accessories from 50.  The immediate concern I have is whether the intake & injection components are compatible with 12's heads.  If there's an issue, you may be forced to use 50's heads on 12's short block.  If that happens you'll need to have 50's heads reconditioned and milled to remove any distortion from the overheating episode.  Hopefully the 12's long block can be used and fitted with the other pieces that came in the car originally.

    It hits 2nd gear really hard and almost throws me into a skid.

    Check that you have good vacuum to the modulator.

     

    WRT the vibration, I would definitely look for a cracked flexplate, loose torque converter, bad U-joints or stuck driveshaft yoke.

  3. Here's a picture of the feed to the rocker shaft.  This is my '38 as it was when I received it.  There is a fitting missing that fits between the block and the line.  As a result, mine had a slow leak.  I was lucky that Leif (on this forum) had an extra one that he was able to send me.

    Here's a picture of the fitting and the screen that goes into the hole:

    The tube screws into the fitting above and provides the mating surface to seal the tapered collar on the supply tube.  The fitting also has a smaller orifice than the ID of the supply tube in order to restrict the amount of oil that is supplied to the valve train.  Check that this fitting is present on your engine, as unrestricted oil flow will flood the area under the rocker cover could be a reason for oil leaking from the valve cover gasket.

    Final (correct) configuration below - no leaks:

    Does the temperature drop if you remain standing still but run the rpms up?

    I didn't really try that, since increasing the fan speed would also increase the heat output of the engine, which negates some of the benefit.  Temp was always under 200° F, so as you pointed out, the coolant didn't boil (despite the unpressurized system).  That was after idling in mid-80° heat for 20 ~ 30 minutes.  Once moving again the temperature recovered quickly.  Also, note the temperature sender sits at the furthest point from the water pump, so the coolant flow is undoubtedly minimum in that area, particularly at idle RPM.
