Do you have any experience with cam in block engines with non-variable valve timing? I wish to know about advancing the cam. I have a double roller timing chain set with 3 keyways: 4* advance, 0*, 4* retard. I am told a 4* advance brings max the torque point down in the rpm range. Will this hurt my fuel mileage as a side effect? I cant seem to get a straight answer. I know most camshafts have a degree built in. If it will hurt my fuel economy, i simply wont do it.
