Doesn't sound like there are to many 350 Argosy's out there.
Since this moho didn't have the engine installation completed I was looking for some help on the 350 configuration. When we first got the 20' Argosy we were figuring on keeping the freshly rebuilt 350 the PO installed but based on how we plan on using the Argosy we'll likely pull the 350 and put in a fresh 454. The moho originally came with a 454 so I would think if we were to stay with the 350 we would need to at a minimum replace the front springs with ones having a softer spring rate due to the lighter engine.
We plan on using it as a tow vehicle for our 31' trailer so a heftier engine should make a big difference.
So now I guess I'm not to worried about how the 350s were installed, now I'm going to need help figuring out the 454 installation
