Re: Does anybody know.....
If I am figuring my info correctly. 45=hp.7= long shaft,e start,with alternator.HF is a production code used from 1970 on HF=1974 USA.<br />It appears HA=USA 1970 HB=USA 1971 And so on but no HE code??<br /> Manual isnt real clear about what year.It appears a 1974 458HF would be 45=hp,8=standard shaft,elec start w alternator and magnapower ignition.HF=1974 USA. USA codes begin with H Canada begins with B<br />Chart is actually kind of confusing.<br /> Motors previous to 70 have no letter code only numbers.<br /> My asumption is 457=67 45hp.thus followed with 2 numbers the first is the variation (long shaft etc.second is production code 2,4,6 is USA 1,3,5<br /> Canada.
