You have no idea what you're doing. You seem to want the motor to idle roughly so that you can show off in front of the geeks down at the local drive-in. Well, the geeks are the only ones who will be impressed. The old guys and the savvy young guys will recognize you as a poser.

There's nothing wrong with using a cam which will make the walls shake if you have all the other components in the motor and converter and trans and rear end to make it work correctly, but you're trying to shortcut the process and make it seem like you've got a hot car when you really don't.

You will have little or no vacuum to operate power brakes and other vacuum-operated accessories and the motor won't have enough power to pull the hat off your head down low. The car will be miserable to drive and you'll look stupid.
