1. Carb bowl level 2. Fuel filter(s) 3. Timing 4. Bad valve springs 5. one or more intake lifters collapsed 6. lobes on cam gone 7. plug wires routed incorrectly 8. Vacuum low.
You should have optimal 17" at the carb port. Lower for high duration cams. I run 5"
The Torker is WAY TOO MUCH for a 350 and those 47 heads. The intake, heads and carb is mismatched. The heads are 1.96/1.66 and will not breathe. The Torker is a high flow/high rpm intake which when you put 750 cfm carb in to a 950+ cfm intake to 650 cfm heads, you get the problems you convey.
What cam???
Without knowing how it ran before..what was done, if you ran it to 5k and dropped oil pressure. You may wish to reflect and post the full shebang.
