If you have several dipsticks to choose from, change your oil & filter, leaving it down 1 quart, and run the motor to fill the filter. Now, choose a dipstick that shows the oil level at add 1 quart. Then add the quart, and check the dipstick says the oil level is correct.
If you do not have a dip stick that matches the 1 quart low, I would choose the longest dip stick you have, cut the bottom off, and remark it with a punch at the add 1 quart level, and another punch mark after the quart has been added. Gene
This is exactly what I did for my 225, as it had a broken dipstick that was about 8 miles long. I used a generic chrome aftermarket Chevrolet dipstick I picked up at Auto Stoned for just a couple bucks, then filed my own notches for full, add, etc. Been that way 8 years now.
