When you jiggle your shaft does it kinda feel loose-in-the-hole?
With the timing lite on the balancer (engine running) does the timing seem to fluxuate in & out(bounce) when held at a steady RPM?
Do you have any kind of MSD box running thru your distributor?
Do you still run points?
Define duel range camshaft!?! (what are the specs on cam?)
Need mo-info!!
ABDFI...could apply

I never wanna kick sand outta sombody elses box butt........you really orta invest 25 bux in a cheap timing light. Properly hooked up AND a timing tape gives you SOOO much info. Consistent info.
Timing light and a vacuum gauge are 'must haves' in a tune-it-yourself tool box.
Jus say'in

If it "runs good" well.....can't improve much on that. (leave it alone)

Remember, this is Don, and you are talking $25

Upgrade - verb:: to replace something (such as software or an electronic device) with a more useful version or alternative.

Seems to me that unless it makes lotso horsepower more or your current sparkalizer is trashed you be throwing money away.

With that said a Pertronix Billet sparkalizer would freshen up the under hood a little.
