I have an old set of plunger cases(1950)Would I be able to swap all the parts from a 1960 motor to these cases??I have a some what complete later motor but I just love these old plunger bikes I have a lot of welding to do on the old cases They are early ZA10 406..

G'day Drew.
There are only a couple of bits that are different. The cush drive unit is, but will fit on a later crank. Stick with an iron head as the alloy head has a downdraft manifold and the carb won't fit on without major surgery.
I have '57 A7SS internals, barrel & head in my '51 A7 plunger.

I managed to do it, if i can- anyone can...!! '52 BA10
What Musky said, and some say that depending on which camshaft, it may interfere with the trough casting I have a 357 and no probs, but it (cam) was ground to tidy it up.
Made an inlet tract extension to fit a 389 mono, but then had to move the battery....

Yep some do, some don't. The 357 was no problem in my plunger cases.
