Tip of the day. When ever degreeing a cam in and you're second guessing yourself. The best way to double check is to put # 1 piston at TDC in over lap and put both lifters in for #1 cylinder, If the cam has 4 degrees advance built into it and you put a straight edge across the 2 lifters and the intake lifter is .020 to .035 higher then the exhaust lifter your fine. If the cam has no advance ground in both lifter should be appox. the same height. If the cam is retarded the exhaust lifter will be higher then the intake lifter. Before degree wheels and indicators were around this use to be the old fashion way of checking to see where the cam was installed. Learned this many years ago from an old timer. This does apply to BB's its a little more complex as the lifter do not run inline with each other. You have to use 2 indicators or record the two heights in over lap and compare.
