216 engine

[motto (RIP)]

I don't wish to state the obvious but surely you've looked at the possibility of using something other than a 216? A 235 will fit straight in, either a low pressure WW2 engine or the later full pressure civilian version. You may even look at using one of the larger Chev 6 cylinder engines, Bedford or even a GMC 270 though they are about 1-1/2 inches longer.

If you come across something you think may fit then ask on the forum. Someone will most likely have done it already.

In answer to your question, I do have a couple of 216 engines in the shed though they need rebuilding. Pick up only I'm afraid.
