year and size of engine please help

[steppinstone]

Hello, I just purchased another project motor from a yard sale The person had no idea about it just that it had compression the whole motor was spray painted white its made by sears, has forward and reverse gears its a two cylinder, the tag in the front of the engine is badly rubbed off.
The serial #( 700355r121332 ) but I can only read the last four numbers of the model # which is ( 0150 ).the top corner says that its a 141 hp and the inside of the engine cover says it a 16.4 cubic inch . Would any one know what year motor this is and model name or any kind of info or direct me to some one that might be able to help .


ps, would there be an impression on the rear of the tag if I took the tag off or should I not try to do that. Thanks paul

Thanks steelespike, okay its a 64 made by McCulloch do you know the model name like Firestone, or Elgin and is this a 14 hp ? I just purchased this figuring that it was a bigger hp then the 1957, 3.6 , Firestone I just redid for my son.

Yes it is a 14 hp.I'm pretty sure it is a Sears, Previously Elgin.
Model number 574.60150.McCulloch was originally Scott Atwater purchased by McCulloch about 1959.The scott guy at "ask the scott guy"may be able to help with parts info and perhaps some history.
