I also believe that if you were to take that piece of vacuum hose and turn
it inside out, and were to drill 3/16 dimples at 7mm spacing and
working in a clockwise motion with a 360 degree rotation ever 1 inch, with a
total length of hose being 1/25th of the engines total cubic inches, and
then turning it inside out again, that it would cause the spark travel
time to more than triple its speed, however doing so might require
that the distributor may need to be retarded just a bit to regain original
timing,,,,,,,,,, caution, this will not work with a MS system as the second
spark may be so fast that it goes the previous
cylinder,,,,
