I was wondering if any one has messed with the cam timing on a 250. I was reading an article that this guy was advancing the timing on all his vehicles and getting much better low end power and mileage and run cooler. but he said he only did it to 1975 and newer vehicles that were normally retarded due to smog. So I don't know if it would work on an older. I have looked high and low online and there is no info on anyone else actually doing this on older engines. Any experts out there have first hand knowledge of doing this? the idea is just to advance the cam gear one tooth.
