Looking through the 1970 parts book for the original part number for a 1970 340 6bbl.cam shaft, I only see one listing under 340 and none under 340 6bbl. Are they the same? My parts book has a date of 1972 in the front so I would think it would include a 340*6, but maybe not. Can anyone provide me with the Chrysler part number of the original cam shaft and do you know does anyone make a new factory replacement for this engine?
