Yep! Quieter than the motors they make now. Had a 51 Ford convertible. If you lifted the hood, all you could hear was the generator brushes buzzing. Wish I had it now. No hydraulic lifters either, and not adjustable. You adjusted them when you built the engine by grinding the end of the valve so you had one shot at getting it right. Much like the push lawn mowers with the L head engines used up until recently. Worked for an engine rebuilder back then. Where I learned my trade.
