Anyone running any of the Xtreme Energy cams in a relatively stock motor. I wanted to get the XE270HR to go with my ported stock heads, and explorer intake I will be putting on. I hear the lobe design is good for torque with these grinds, and want to know anyones input on this cam. I will be getting the one for the 1.7's. The specs are: 270/276 advertised duration, 218/224 duration at .050", and .544"/.544" lift. Anyone have this cam? Where is the power made with this cam? Any low rpm driveability issues? Say like 1500 rpm in fifth gear? Thanks for the help, Chris p.s. Anyone see any problem with piston to valve clearance? It will be stock pistons with a stock valve size.
