Pan or Shovel?
Thanks to Alex Blair for these pics of his Pan/Shovel. It appears as though this is a panhead, but the intake manifold suggests it is a shovelhead.
PFI install on the pan/shovel. Notice the machined inlet on the backing plate. This helps decrease pressure drop and increases overall air flow.
The PFI motor mount has the fuel pump mounted on the back side. Cast iron cylinders create excessive heat, so an insulated pump cover is available to reduce radiated heat transfer.
