I have the same problem with my '71 350/350, A/C, HD cooling, 190F thermostat, have an insulator on both the fuel pump and carburetor. The last thing to try before I go with Holley Sniper is a Carter P4070 fuel pump to push fuel through the mechanical pump. I have observed that running cool water over the mechanical pump causes it to run better.
