Thank you for your responses everyone. For all I know the engine might have had modern detergent oil ran it it. My wife's grandpa built the car, in 1978 I believe and it hasn't been apart since then. He passed away about 4 years ago and nobody knows for sure what oil he used in the car. I'll drain the non detergent out and replace it with something better. Should I slowly transition to detergent oil, maybe like half and half first, then on the next oil change go full detergent?
