There is information on the orientation of the oil dipstick tube in the block published in my copy of the '69 A.I.M. (in UPC 6, Sheet B1). It shows the curved portion/dipstick handle pointing forward and slightly outboard per a notation in View A that reads: 7 deg's, +/- 5 deg's, or roughly towards the left front headlight. However, I've come across many underhood photos of supposedly original cars that show in most cases the tube is oriented nearly vertical, such that the upper end of the tube is positioned between the cylinder head and the air pump distribution tube assembly. Could this be one of those cases where it doesn't really matter how it is oriented as there are many documented examples showing a variety of orientations?
Thanks for the help.
