I picked this up along the way....
This setup is also what I did...Just some more good info on mechanical fuel pumps... if you want to run a 4bbl or double pumper you should run the fuel pump off of a 1984 L6 250 which had a base pressure of 68psi instead of the 46psi of all earlier L6 250 mechanical pumps. As well boost referenced mechanical pumps are good to 1214lbs of boost after that, they cant keep up.
