I'm rebuilding a pretty much stock 59AB and I have just two questions (so far).
1. With a mild regrind cam and new lifters and stock springs, should I use a zinc additive for break in?
2. Should I installed hardened valve seats?
I had my crank reground 4 or 5 years ago and put it in a box to store it. the box is resting on the floor and the crank inside is parallel to the floor. Is there any truth that all crankshafts should be store vertically?:confused:
