correct timing tape 67 327/275

Guys - I want to buy some timing tape to more precisely check my mechanical and vacuum advance. I have a completely stock 67 327/275. I see they sell a 6 inch and a 6/34 inch. Well, being lazy I ran a string around the circumference of my balancer (pulley still bolted on) and I measured roughly 19.5 inches. Getting some use out of my geometry formula for circumference.....19.5 inches gives me about a 6.2 inch diameter balancer. Should I have a 6 inch balancer then on this thing?

thanks...JD

If you know the circumference, can't you calc the advance and make marks using geometry to figure the % of the circumference per degree?

I would use the 6", it will be close enough.
Depending on your budget, timing tapes are a pain. They like to come off.
I use a summit cheapie balancer, have had it 3 years now, and it works great. Same diameter as my factory 327 balancer, but fully degreed from zero to 90, plus every 90 degrees all around. I use a summit adjustable poitner with it, works good.

Jim- I guess that new balancer would not work with my original timing cover....? I believe as I have learned on this board that the keyway was moved 10 degree or so relative to the marking on the balancer.

Alan - Yeah I suppose I could just take 1/10th of 19.5 inches and call that 36 degrees...problem is I think I did a half *** job of measuring with the pulley still being in place. Oh well, guess I should stop being so lazy and take the pulley off and do this job right!

With a dial-back timing light, you don't need a timing tape or degreed balancer.

Except that most of them are horribly inaccurate.

Possibly. However, my Actron CP-7519 ($75.00) is within one degree full-scale of my neighbor's $400 Snap-On dial-back light; I can map the full mechanical and vacuum advance curve on anything in less than five minutes with no add-on timing tapes or markings with it.
