My engine is a 1971 340 (august I think). Externally balanced.
I have a manual for 1968 and the only thing it says regarding identification is whether I have a Maltese Cross stamped on the “numbering pad on the right side of the block” . It may have undersized one or more bearing journals by .001. If it is stamped with that cross and an X All of them are .010 undersized.
Is this Maltese Cross Id still true in 1971 or 72? Do I need to worry about it if it’s heading for the machine shop? Where is this numbering pad? Will any LA crank shaft work or is there something specific I need to target?
Thanks in advance
