Although Nasty and a few other sites show this only in '69 as a B-Body code, if the original and/or a '68 HH it's a 327/250 Hp 4bbl w/ a 2 speed Powerglide.

Here's all 1968 B-Body Chevrolet Suffix Codes below from Impalass.com...click here for Rpo's etc http://www.impalass427.com/68RPO.htm

Thanks Pete for the information.
This is a one owner car with the original motor.
The odd thing about this car, is it has a turbo 400 kick down switch mounted next to the carb and the shift indicator has D L1 L2.
This car has been sitting outside in NH since 1977 because one of the brake shoes locked up. What a shame!
I will be going to NH on the 20th to finish stripping the car of salvageable parts.
Thanks! John
