No --- As Todd stated -- that only works at drag racing where you're able to shut down after a WOT run....
There are also ways to read timing on the spark plug "strap"... by where it changes color. The color change needs to be a line right across the apex of where the strap makes the turn. But now we're getting really old skool in the pit dyno.
Hope the distributor is the issue -- certainly points to an issue.
What color bushing you running? I would think BLACK.... which would be the 18* stop bushing... and with good heads and good fuel your total timing should be maybe 34 to 36* all in at 2500 to 3000 rpms??
