Series.one GM transmission options?

How do I know the high stall on a converter what is one looking for # etc??? I never got into this subject before so I’m new to the converter theory??? Need some teaching.

A 2.88 is about 6% “taller” than my 3.07. It should be OK as my 3.07 has no trouble up hill/down dale. Paul.

Me too. I don’t know much about torque converters.

It’s a GM Turbo 400 like XJS had after the BW12… Has a bolt pattern for a V12 so it won’t fit an XJ6 without modification.
