Lar,
The center-to-center spacing of the Olds F-85/Buick Special engine
of 61-63 is 4.240" Also the original Buick V-6 of 1962 (198 C.I.). It's
hard to imagine the Rover 3.5, 3.9, or 4.2 being any different, though I
have not checked it out. Also I suspect it is very likely that the Buick
300 and 340 are the same else how could the cranks and cams be so easily
adapted from one to another.
It should be a relatively easy task to measure this on the top
block surface because the distance from the edge of 1 cylinder bore to the
corresponding edge of an adjacent one is identical to the center-to-center
spacing. Hope I didn't misinterpret the question.
Regards, Dave
