I’m wondering if it’s the cam that gets advanced 7 degrees or the overall timing between the cam and crank that gets advanced 7 degrees. I bought a degree wheel and plan to try to make one myself. I’ve got a bunch of extra sprocket so if I make one I can make moreOn the chance someone has one of these, I would like to get my hands on one.
I've had one for years in my 2000 C10, and I want to put one in the new to me 2003 C10.
Changing the exhaust cam sprocket 7* advance's the exhaust cam 7
