Check My Cam Degreeing

If you have the degree wheel/pointer properly zeroed out already...... post the results for:
Readings taken at .050 lifter rise from the lowest point....... on both an intake and ex lobe for the same cylinder-
(Or take a pic of the degree wheel & pointer at those 4 positions)

Intake opening...... BTDC=
Intake closing ...... ABDC=

Exhaust opening .. BBDC=
Exhaust closing ... ATDC=

That will provide everything you need to determine lsa and intake c/l

I thought the SB 508 cam was only offered with a 108lsa........ but I wouldn’t swear to it.
I know it was offered as a 108 or 114 in a BB.

The SB 484 was offered as both a 108 or 114.
