I had a 90 Holley on a Swaymar manifold on a 3 litre and it was the same way round.
In the end I ditched it and went back to a 2 barrel Weber, the Holley was too much carb for the motor despite my lumpy cam and big valves. Ran fine at the top end but nothing at the low.
I had a few 2 bbl carbs on the standard manifold: Weber 38 DGAS, later 40DFI, later Holley 350, later Holley 500 (best for race, thirsty for the road), later re-jetted Holley 350 and my current setup is the re-jetted 4 bbl Holley 390.
I don't think. Holley 390 on the original Swaymar inlet manifold has this orientation. Bought a Swaymar/Holley kit brochure in 90s and have a lot of pics from internet with the same position. But you're right that inlets from the other producers have a different carb orientation.
so this is a replica then ?

Jesus god what is that whine, a bad water pump? Spoils all the other sounds.

water pump was new. This sound comes from steel cam gear. It disappeared during a few days.
