Cams, mild or what?
Hey all,
Im thinking about putting a Comp Cam into my 460. Ive heard the term mild cam before. What does this mean? I was told that if i also change my cam, it would make the exhaust have a explosion pop sound instead of a rumble. How big or what of a cam would do this? Im also trying to understand all the numbers on this. It say Duration @ .050" intake is 253 degrees and exhaust is 253. Lift intake is .585" and exhaust is same. What does all that mean? How big would be too big? Cause i know that if its too big, the engine will stop if your foot is off the accelerator. Thanks a lot everyone!

That is actually a big cam. I have one a little smaller then that and I have a definate lope at idle. The duration is pretty large. Are you running stock reworked heads or did you go aftermarket? You are deffinately going to have to run headers, improved intake/carb, and a stall TQ convertor to be able to run that cam. And possibly change out your rearend gearing.
The term "mild cam" is actually a cam that is slightly larger then stock spec's.

Another note on the cam.... If you have stock heads and you haven't done extensive porting work to the exhaust side, you want to run a split cam. I.E. the exhaust duration and lift is slightly larger then the intake.
