1974 Thermoquad, 360 HD Truck , Rebuild adding performance modifications
This is a K&N Holley stub stack. It’s not a velocity stack, but I have seen them put into velocity stacks. The problem is one would cover the air bleeds into the primary boosters. Air bleeds are above the venturies in a Holley.
