5.7 0r 6.1 with msd hemi 6 and carb

I'm with myduster here the combustion chamber design of the 3g hemi doesn't require anywhere near as much timing as you would think if the afr is in the correct range for the combo. N/A 5.7 should be around 12.8-13.0 wot afr and around 28-29 degrees for peak mbt.
