What small cam do I have???

If it runs good like it is. Use the same parts. The biggest problem with cpls is the biggest majority of old good running engines were done by mix matching parts. In these parts old timers used to what we and ZZTop call “Coon Tune”. In other words. Top secret sects of the trade. My uncle tuned the pump and timed the 350 in my Pete. I have no clue what it is set at. It runs good, does not smoke, starts easy, pulls good and gets 6’s for mileage. I had the pump rebuilt 10 years ago.due to epa the Pump shop had to put it back as a cpl160. It ran down on power and got 5’s. They gave me back all the modified parts they removed from the pump. I put them back in after their year warranty. Other then the #7 button i have no idea what the spring color codes were, but It is nowhere near the cpl 160 it was born as.
Cummims NH’s are like smsll block chevys. Easy to work on, modify, snd ain’t none of them “stock”.
