Can anybody tell me what year this motor is ?
Code= zn655177

Oz,what you'll have to do is get the code off the dist. pad.The code consist of a letter and 2 or 3 numbers.a=jan. b=feb and so on.If there's only 2 #'s the first # is the day of the month and the 3rd is the year.Or the same thing if theres 3 #s.Example J23=Oct 2,1963 or F126=june 12,1966.theres also others variations so if you have any ?? let me know.Doug

Sounds like a 73 or 74 big body 400..Does it have 4X heads??

Thaks for the help. It's a 67 OHC.
