For 85 - 8deg. advanced.
If you check out prior posts, most setups are between 6 to 8 deg. advanced.

What do you have done to it? You can't put a teaser like that and tell us at least some of what you have done.

For me personally 9.5 has been the best, yet I also have not tried higher yet.

Re: L98 timing (DADDY D)
Setting the correct timing assumes that the Harmonic Balancer hasn't slipped and that there is no slack in the timing chain.
