Does this prove David Vizard's 128 lsa formula ?

My cam from howards said to install on a 103, but dot to dot gave it a 109.. is it normal for a cam to be that far off? i checked it like 5 times to make sure it wasn't me. Emailed howards and they said advance it to 103 so i did.
Yes and no. It really doesn’t matter - Why?

You have seen here, read everywhere and been told over and over again to do what????

Degree your cam! Then you know it’s right.

My MP .590 needed a 1* adjustment. Oddly enough, that was the only cam key I had on hand.
