Yes Jeff it SHOULD still be at 34* at wot, BUT, it ain't necassarily so. As these guys said, before the argument, the clearances at idle can fool you into thinking you're setting the timing one place, but actually you're locking it down in another. That's why your timing appears to retard a little, as you speed the engine rpm up, all the clearences settle down, and you see where you've actually locked it down. Setting the timing at 3000 rpm is a good idea, cause it settles the clearences, and lets you see where you're actually setting timing at. Hope this helps.

I do use a Donovan gear drive, and MSD pro mags dont have springs/weights timing curves, so I didnt gut anything.
Any other comments to put your foot in your face?
mine is the same,but made by erson

Thats why I said rev the motor and look at the timing during the up swing of the RPMs.
The timing during engine acceleration is the timing that will be seen on the track.
Now, that being said, if you use engine RPM acceleration to note timing, and then double check it at 3,000, you then know that they are the same. Motors and tolerances will vary.
