While we're on the topic of engines, I need your expertise, Arthur.

The engine in my 1974 coupe', which I suspect to be a 1975 engine according to the casting in the head, has the serial number 110 922 12 029 278.

Can anyone dig the information up regarding manufacture date?

ja17 has a head from a 1975 engine and I believe it will work. Neither one of us (and ja17 most definitely doesn't) wants him to go through all the hassle of yanking the head off a perfectly good engine if it won't work.

Joe thinks the 1975 models went to a lower compression whereas my Motor's manual (yeah, yeah, it's lied to me before) says it actually has a higher compression. Just looking for a little clarification.
