The year of the motor is 1954 I think it came out of a car because it had no front motor mount, I had to drill front holes. Last summer a lifter started to make noise so I adjusted the Top end everthing went good for about a week, the noise came back I took off the valve cover and ran the engine, two push rods are not spining like the rest and I had to adjust the valves two more times in three hundred miles. Thanks for the input.
