1970 340 crank pulley part number

[TGGodfrey]

Anyone happen to know what the stamped number on a 1970 340 2 groove pulley should be?  I can't find any info on it.

I have the wrong pulley on mine.

Thanks

I don't think they have a stamped no in 70. I've seen it in later years.

Maybe that is why i can't find anything on them.  I have a 72 2 groove and it is stamped.  Seems like the only difference is the offset hole on the 70 and the even spaced holes of the 72.

Thank you for the help.
