Hi Grumper,
waaay back in the early 60's, drag racers would cut a slot in the firewall,
and stick and "arm" off the dissy, which they would move
to retard the timing at high rpm, after they hit high gear.
Crude but effective.  The only caution, was exhaust temps
increased noticably.  Not a big deal for a few seconds..
