Rick,
You will receive many opinions as this subject has been much discussed on the
forum over the years. Heres my 2c's
I agree that you should use 90 hypoid for the steering rack, gearbox and diff.
Several years ago I switched over to a synthetic for the gearbox as I was led
to believe it would be better for an aging set of gears. It does seem to
shift smoother.
I'll leave the break-in oils to others who know better but I would include a
zinc additive such as found in the Lucus' break in oils.
For normal everyday engine oil I use Valvoline VR1 20/50. It has a high zinc
formula which is much needed in our pushrod engines. I think they still
produce two versions, a road and race formula.
