Has anyone heard of why a 340 block would have no numbers stamped on the front?
The engine in my 70 340 cuda was swapped out early in its life by a Chrysler/Ply dealer. Its a late (October) 71 casting, with a steel crank, 2.02 J heads. There has never been any numbers stamped on the pad above the power steering pump where the size and vin should be.
Someone once told me it could be a warranty block. Has anyone heard of a "numberless" block before?
