If the engine has the OEM dipstick tube I can get you the measurements on the dipstick.
Al alternative method is to change the oil.
Add the propper amount of oil taking into account the extra needed for the oil filter.
Let's assume the book calls for 4 qts plus 1 qt for the filter. You put the 5qts in and drive it till it's up to temp. Let it sit for 10 minutes and pull the dipstick. Where ever the level is, is the full level.
67 Dart 273 dip stick ( this only works if you have a stock 273 pickup and pan)
