went with a comp 280 magnum cam is the idle the same as a mp 280-474?

About 20 years ago I had the comp magnum 280 can in a 327 Chevy. Idle wasn't to bad. Sounded healthy though. Had great power from 2000 to 6500 or so from what I can remember. Took off hard and pulled all the way through. More bottom end than the stock can by a long shot. And way more top end. Had a 4 speed manual close ratio Muncie. 3.00 or higher gears. But like I said pulled way harder down low than chevys stock cam. Its not a 318 or even a Mopar so I'm just sharing an experience. No idea or clue what that can is like in a 318.
