Re: V8 Camshaft Durability
I have run delvac 15w40 diesel in my SBC since I built it about 10 years ago. She was my daily before I retired. Flat tappets are still there. If you are running a solid lifter they make them with added EDM holes that oil the cam face as it runs. I used those and this is an 8k RPM motor that used to see a ton of stop and go traffic. Think concert traffic.
