they do not have the vacuum port "out of the box"...the vacuum port is
added...these are fully prepped A.J. Simms(lowbugget.com), but the ported
throttle body is from John C. at aircooled.net (

the vacuum "signal" is correct and can be verified with a strobe type timing
light....the vacuum advance on the Mallory is going "full advance" at justa
crack of the throttle and drops sharply to nothing once you open it
up...once the rpm's "level out" and you have taken pressure off the
"throttle" the vacuum advance creeps back up(part throttle setting)....the
throttle response is much better than with the old distributor(009 with
pertronix) and i expected it to be...no disappointed at all...check out the
above link to ac.net for more details....
