Hello everyone,new here and new to the Datsun engines also. Is the Datsun engine and the Nissan engine made by the same company? I have an older 4 cylinder engine I want to use in a machine I'm building and need to find some specs like hp,rpm range, torque, and maybe the year it was made. It has nissan on the valve cover but I was wondering if it was similar to the datsun. Or maybe the same. As stated I know nothing about either so I figured you guys would know of a link to the specs. The numbers are A 14 ( I think that's a 1) then 735581. It has an alunimun head with cast iron block ,carburator, and old style distributor. Any help/info wil be greatly appreciated. George
