MG TD TF 1500 - High lift cam points Dwell

Just doing my fourth rebuild ( its a long story )
and was checking my points. Does anyone know what the dwell angle is for the high lift dizzy lobe?
I thought it was 60 degrees but this has resulted in 0.007" point opening when it should be 0.015"

58-62 if you have the high-lift fitted to TF.

I don't remember exactly, but if you have an older 3-wire meter you may be reading the complement of the dwell, 33-27 degrees.

Set the points to .015" and see what the dwell is.

Is the car negative earth?

If it is positive earth and you are using negative earth tester you will see the complement as Tom suggested.

28-32 would be complement of 62-58.

I complied this information form data originally put together by Bob Grunau.

It looks like my dwell meter is a three wire and I have been trying to set it to Bob Grunau's advised 57-63
degrees of dwell when i should have been aiming for
33-27 as Tom pointed out , hence my measurement of .07" instead of .015
Thanks all
for your help !
Cheers,
