My dipstick was not stock. I put in 6 qt of oil (I have a filter) and filed a notch on the dipstick where my "full" would be.
My dipstick did not match the oil level either. I added 4 qts to the newly rebuilt engine, then filed a line for the low level, added another quart and filed a full level line. My engine at the time did not have a bypass filter. I’ve added one since.
