Russ, You say you haven't actually checked valve timing....the way I see it, if you're a tooth off, 44 teeth on the camgear divided by 360 degrees means each tooth gives just over 8 degrees. That equates to 16 degrees at crankshaft. being one tooth off would also advance the dissy by the same 16point whatever degrees. Then, depending on exactly where the points plate in distributor is located, could easily make up the rest of the ign advance you're seeing. As others have said, you need to degree in the camshaft first. And yes, a vac gauge will show if your valve timing is out, a very handy diagnostic tool I reckon. Good luck, Brian
