I am just curious....I am at .750 lift now on the street/strip car, and wondering how the cam & bearings are holding up. Lots of spring pressure already, and I know guys are running .800" lift on the street these days. The only way I can imagine that is with a thicker cam core...I may have answered my own question there, but I am curious what others have done. I want to make this car somthing I could take on Drag Week. So when I look at cams next time, I want to be able to figure out if I need to go to a 55mm or 60mm core or maybe stay where I am at.
