Looks like I did the right thing in asking about it here; many helpful tips. My only experience with this type engine was in the late 60's or early 70's when a taxi company had a fleet of Ramblers with I think (?) the 258 engines. We did the service work on them and I don't remember having to ever do any major upper or lower engine work, just the usual tune/service work. One thing I won't forget is the oil filter was on top of the engine and upside down meaning a mess with each filter change.
