There is nothing more miserable to drive than a cam that is too large. Fouls plugs, jumps and jerks, etc. Mopar had a well balanced cam in the 383 that came in Road Runners. Had a slight shake, ran well. I'm sure the lift and duration numbers for that cam, heck, maybe even the cam itself, are readily available. But, this is going on memory from over 30 years ago, I might think it's "too much" cam for my tastes now that I'm older and more interested in driveability than "sounding bad". I know I've got a Chevy II right now with a 500 lift cam and it's just no fun to drive.
