I'm a little puzzled here. If the distributor was installed several teeth off,
isn't the only thing that will do is change the position of the distributor
body, and hence, the secondary towers of the cap in relation to where they used
to be? Spark has to occur somewhere near TDC for the engine to start. Engines
with helical cut teeth on the distributor gear can be installed in any
position. The only issue is that the tower marked #1 may no longer be connected
to #1 cylinder. I am not familiar with timing marks on those engines. Are they
on the front pulley or the flywheel? If they are on the flywheel, don't most
flywheels have an offset bolt pattern and/or a dowel pin that would prevent
incorrect positioning during re-installation? Sorry for jumping in without
fully researching.

I think Randall's point was, you could have installed the pulley wrong: the
hole should be opposite the slot for the woodruff key.
Could you have gotten the distributor drive one tooth out where it engages the
cam? If that is the case, it is fairly simple to correct - or you can leave
it as it, just bearing in mind the timing will always look wrong.

Thanks Randall,
40° was just a guess, the mark is about at the 2:00 position. I am using the
hole in the pulley as the TDC mark, there is also a file mark there.
I turned the dizzy clockwise until it started to stumble, then brought it back
to the best smooth RPM position. First road test was great, compression at
175 across 4. Can I leave it there? If not, what should I be looking for?

Sounds to me like your TDC marks are wrong.
If the issue is the front pulley being assembled wrong, it would be off by
60 degrees, and so you're still about 20 degrees fast. That is likely to be
an issue.
40 late isn't going to work well either.
