LA motor with no fuel pump boss?

Sorry for the Off Topic.
I picked up an '83 Ramcharger as a parts donor (for a '76 Power wagon), and the small block in it has LA heads and intake, but the block has no provision for a fuel pump.
Did they ever make an LA with no fuel pump boss?
This truck is... seriously hillbilly rigged, and I have a hard time believing someone would have gone to the trouble of swapping LA heads onto a Magnum block.
