i have a kinda off topic question but i just cant figured it out. me and my friends are trying to figure out how exactly the second set of cams kicks in on a corvette ZR1 with the really nice lt5 engine engages. how does mfliping a switch in the inside engage the second set of cams? i cant figure out exactly how it just "kicks in" i thought that it was always spinning with the timming belts. this is driving me nuts not knowing this, i cant figure it out. i thought that it just engages better because they are in syn at a certain rpm, anybody know?
