You're right RRR. You said "anything over 120 is pretty good".
And you are right, for a well-used stocker.

Rumble; I agree with the fast statement.
But the owner said it was a "fast engine" in a 73RR. There is a fast engine,and then there is a fast car.And that lazy engine is in no way," fast". Nor could it possibly have been "fast" in any stock bodied Mopar, never mind the RR.Well it mightabin faster than a lazy /6! lol
