Holley/Demon Carb stumble

Ok so i think i need to update this thread so we are all on the same page.

Started with a 850 Mighty Demon carb.
Problem started out as a major bog at the starting line. which bigger squirters did not fix the problem. (Taller tires and a tighter Torque Converter is when this demon start to give me grief. Work grate up to that point)

Bought a proform main body that was smaller ventures, with hopes that it would start the booster sooner and stop the bog. this was a big improvement but caused a lean pop at mid rpm of 2ng gear. jetted up and problem when away but now thinking that it is to rich.!?

cars 60 foot was the same at 1.7XX but was a bouth a 1.5 miles per hour down in the 1/8 and 1.5 tenths slow as well. Bad air day was some of this loss.

Wanting to have a good know base for the fuel/metering, i have been trying to find a couple 3310 holley front metering blocks to try.
found one and am still on the hunt for another.
