I bought a car with a motor that had supposedly had an lt4 hotcam installed in it. After pulling it, I'm unsure if it's actually a hotcam (which is a bummer because I was supposed to sell it). Does anyone have one laying around? What numbers does it have printed or stamped on it and where? How can I determine what the specs are of the cam?

 

You could always whip out th ecalipers and measure the lobe lift. Remember the LT4 "Hot" cam setup used 1.6 rockers, so calculate accordingly.

 

it turns out to be a regular production LT4 cam.
