Since I don't hide anything or have secret technology I will tell you precisely how I did it.
Wide band oxygen sensor meter so I could run a real lean tune around 16.5:1 air/fuel. Replaced the quadrajet with a edelbrock 650 only and edelbrock air gap intake manifold. Because I know how to tune and have to tuning kit for the edelbrock carb. Thermostadic intake and EOC.
Timing curve was stock profile, advaced 4 degrees beyond the factory recommend base advance.
I have posts going into great detail on all these mods.
Was getting 12 to 13 in town and as high as 16 to 18 on the highway.
New suburbans with much smaller 6L engines, OD transmissions and aerodynamics don't even do that well.
I figured I would be lucky to get double digits in town and 12 to no more than 14 on the highway.
