Breakin your motor for 3000mi. then take it and see how it runs all tuned.
The sound ain't goona take you down the 1/4 faster the combo will.
My car has a little cam slight lopey idle but it runs like an animal,cause the cam matchs the rest.
If you do change the cam match all you parts comp,valves,gears,tranny,converter,etc...to your aplication.
You can put a nasty cam that revs to 6500 sounds like a heard of elephants.But w/ say 3.08 gears you'll never see peak performance(maybe on the saltflats).
The idle carecter should be something that comes w/ the cam not the reason you buy the cam.
