If that was my car, I wouldn't run it until I figured out where all the fuel is going. A well tuned 302ci carbed engine should get around 12 around town and in the low 20's on the hiway.
Check your plugs. My guess is that they are either black or wet (or both). The MSD 6AL will still fire a plug even if it is soaked in fuel. You are shooting raw fuel directly into the cylinders and will wash the cylinder walls in effect wiping out your ring seal. Then, the gas will dilute your
oil and you'll lose everything that depends on
oil for lubrication.
