HELP! I have an MSD pro billet 8365 HEI distributor on my stock '87 454 and have no idea on how to set it up. The vacuum advance is not in use. Do I set the timing at like 4 degrees BTDC and utilize the centrifugal advance weights or pin it at full advance, say like 22 degrees? I am also not sure on how to "pin it" at full advance...and if it's set at full advance will I overheat while idling through the no wake zone?
