No Mitch the ams pulley had nothing to do with any of mine and your problems . The ams pulley is retarded 6 degrees from 0 so if you set timing at 15 degrees you will be running 9. Yes its your machine work and clearences but I had to.change a faulty head gasket and rod bearing from your build after only 5000 miles of running 18 OSI and now tested and proven only 9- to 10 regress of timing . When I should have been running 15 degrees which would have made things worst for the issues I was having with your work. Mitch I like you and enjoyed talking and working with you but in the end I had major problems with the engine you sold me. I wish I would have not had these issues. Or maybe that you would have fixed them I'm about to.fire up the.second engine that I got for my Buddys car and I hope he don't have berring failure like me because he won't be so nice about it
