ive seen from 11:1 to 13:1.........
with a mild advance curve where should i set this thing ?
Is the dyno the only way to know ?

Thanks

It's a *by case* issue.
You have to tune to what you particular combo wants.
A dyno can save you some time, but, you still need to finalize it in car.
For Neighbor hoods.
11.5-12.5 for S/C T/C
12-12.5 for N/A
but there are exceptions to those.
Plug readings, and time slips are the final answers.

I guess that 11.5:1 is better then with my T68, 75 lbs, 270-276cam
Thanks
