one of the old chrysler fiends related that when mopar couldnt give away the 426 wedge motors (because of the hemi) to get rid of the backlog they restamped the pads as 413 and started throwing them into newports as a 413---yeah and we have all heard stories about uncle harolds hot rod newport---i was told to look at the block castings which will still show 426----on a related note i found a dana 60 under a 1972 dodge truck with a pinion snubber on it---made me wonder if it was something else thrown out the back door....bob
