Couple of crazy Argentinians staring a Phase II Y-Block after 27 years of deep sleep.

Sounds still like a real Y with those revolutionary high tech inline intake runners.

Reminds me about time when we got our rat rod running first time. Good friends around and all cheering up when flames fly from exhaust pipes. Good times... Wonder where that Argentinian engine ends up? Some truck maybe?

It would be interesting to get a hold of one of those just to see how it actually compares. Build them as equal as possible to see which has an edge, if there is any at all.

It would be cool to build to motors, a Phase I and a Phase II just the same and see what has an edge.
I like the Phase I better, it's a personal taste thing, and also because of the parts availability. For example: There are no four barrel intakes for the Phase II, and "hot" cams are also in short supply.

Then the intake would probably be the determining factor. Or just use 2 barrels for both since the head design is really what will be compared. The cam may not be an issue. If cam blanks are available, a custom cam can be ground. And if blanks aren't readily available, it seems like one could be made. Not exactly cheap, but for the sake of testing, it should be possible. Do you know if the cam blank is the same for phase 1 and 2? It would be real easy if they are the same.

The cam blanks are the same, as the block is the same. Firing order is the same.
A custom cam would have to be grounded. Compression would be another issue, as the Argentine engines were low compression due to the low octane of their gasoline at the time. The higher compression ones had 8:1 due to domed pistons.
Just for comparing, our Y-Blocks here in Brasil with flat top pistons had 7,8:1 compression (1956 heads) but the heads were pretty beefy and could accept well some modifications to kick compression up. Material also has to be taken from the intake contact surfaces in order to make everything to align again. On the Phase II I don't know how much can be taken from the heads, had to get a set, and make some tests.
I think, the easiest would be to build a Phase I to match the specs of a stock Phase II, same cam configurations, same compression, same two barrel carburetor, and so on.
