three hours. I was very uncertain at first and spent a lot of time double and tripple checking things. I also spent a lot of time messing around with loosening and tightening the crank bolt to rotate the degree wheel before realizing I could just bend the wire instead. Every time I removed the crank bolt(even with a 1/2" impact wrench) it would move the crank also which made it very hard to find TDC.
The driver side cams including finding TDC of cylinder two took me no more then 30 minutes with most of that time spent on setting up the dial gauge just right.
