Rookie question here. I bought a new set of Harland Sharp roller rockers from a friend. They are supposed to be 8-1.5 and 8-1.6. My question is how do I tell the difference between the 2 ? and how do I set them up?
I would look at the cam and heads before I decided where (if at all) I decided to use the 1.6 rockers. In most applications I would think you would want the 1.6 on the exhaust to make up for a less efficient exhaust port.
The engine was built a long time ago by my father-in-law. No one seems to know exactly what cam is in it. All he can tell me is its a mild cam.
