340 oil pan

I have a jam-up and jelly-tight 340 duster that I'm about to unlease on the universe, but first I have this oil pan question, which is this; does this engine have the same oil pan as 318?. It seems as though the sump pickup is about 3/4" deeper than the pan so it won't fit horizontal on the bottum of the pan .
When we took off the pan the sump pickup was canted at an angle an I suspision that this is why I couldn't get the pump to prime (sucking air) the pan has a stamping 294 which checks as the correct number for this pan. has anyone had an issue with a too shallow pan or the pickup being canted to not suck oil?
