Who Makes Cams

Damn,this is deeper than I ever imagined !! I just want an awesome cam for street light to light confrontations and trips to the strip !!I had one of Mopars 528/278 (?)cams that was fun,but the gear shattered on me !! I ended up with a 468/276 that was still peppy enough,I just want to take this motor a step or two higher !!Maybe even look at a Paxton ??
