List,
I received the following note from Bill Perry at Rivergate in response to
the question about using the 210 clutch cover on a 1380.
Bill's opinion is one that I value so thought I would pass it on to the list
for comments. He has me rethinking my desire to switch to the 1380.
Comments from anyone on the list that is currently running a 1380 would be
considered helpful.

The change to the Datsun 210 clutch works fine-if: You do it in connection
with an engine overhaul so that you can have the crankshaft balanced along
with the flywheel . Otherwise you can end up with a badly out-of-balance
flywheel/clutch. They will need to balance the crankshaft, add the flywheel
and balance the assembly, then add the pressure plate and balance again.
Pretty normal procedure for race engine balance shop.
You will just need to measure clutch throwout bearing clearance to insure
adequate clearance. Be sure to get 3/16" minimum. This may not require
modifications to the linkage.
1380 engine--I have heard from lots of my customers that have 1380 engines,
and I can't seem to recall any of them that are happy with the engine.
They all seem to have severe blow-by problems, and some have proved
unreliable. I love the .040" overbore engines as they are just as reliable
as stock. I certainly would not go above 1340. Some customers have told
me they would never again have a 1380. I have never owned one so this is
second-handed info. I suspect the huge bore just takes too much of the
strength out of the block, and may give unstable cylinder bores.
