non-A/C is really rare for '72.
A GREAT muscle-car- the Buick bench seats are really comfortable with that center arm-rest.

----I guess I'm asking weather the cam and compression and other similar stuff is the same. I know 72's were measured for advertised horsepower differently than 71's. Aside from the pump is the 72 engine the same as a 71 and why?...….Bill S
