Just curious if there is a chart somewhere listing HP and CR of Olds 455's
I have a 455 # 396021F from what I understand it is a 68-71 which I am sure with some looking/cleaning I can find a date code ?
Thanks in advance !

 

Don't know of a chart anywhere. But what letter heads were on the engine? That might get you closer to the year and narrow down possible CR.

I will check , actually I found the chart I was looking for @ Oldspower,
big torque reasonable CR I think I am going to like this Oldsmobile stuff !
