regardless of which year it is, the engine of all those years are really good engines.
The 71' is still a forged crank,(and 72' for part of the year, all if a four speed engine) The compression drops, yes. Bu they are still really well built. With the gas made today, I rebuilt my 71' with the 9.5:1, and it is a dream to run. I would be happy to have any one of them.
