Years ago there seemed to be a lot of concern about rebuilding an engine
and having it ruin itself because of ballooning torque converters or
something like that...

Which was getting destroyed and why? And what steps should be taken to
prevent problems?

I'll be building a spare engine this summer and would like to do it only
once. My current engine is approaching 300,000 with one known backyard
rebuild...thus it is obviously getting tired.

Thanks

Mike in NM

Mike,
I ran int this issue with my Cad engine few times.
First the crank must have the thrust bearing surface almost perfect.
Majority of crank grinders do not put much enpasis on this as majority are
for cars and pick up.
There are New style thrust bearings that work much better, also one needs
to know how to pre load it so it is lining up.
Also starting up engine with trans modulator disconnected will showe the
torque convertor into the crank.
Avoid running engine in revese or lower gear selector as the line pressure
will go up and shove converer forward.
Newly machined surfaes are problem,
Do not lug the engine, better to rev it higher when driving.
