If you have to do an engine rebuild, you can convert it to Vortec heads, 4bbl intake and add an Edelbrock 1409. Money yes but probably worth it if the old heads have to be redone anyway.

That would certainly be a definite consideration.
Any idea of a ballpark cost these days for those three ticket items.?
I'm sure there'll be other items (brackets, lines, etc.), but I'm fine with that.
What is the consensus on the HP increase (pre-Vortec 2bl vs. Vortec 4bl).?
Keep the V-belt accessories, or would those need to be changed also.?

I'd keep the V-belts, serp belts can have troubles of their own...
An intake and a carb, is going to be at least $1,100--$1,300 depending on if you buy new or used
Cyl heads are about the same price for pre vortec or vortec if you need remans.
If the old heads are in good shape, you can save money sticking with them
And, you could add a 4bbl cast iron intake and a 4bb carb for a lot less than a full change-over.
If your original heads definitely need to be replaced, the full change over makes sense.
4bbl carb may add 25-30 hp on the top end
Vortec heads may add another 25 hp to that

Thank you guys, for all your feedback on the engine picture.
It seems unanimous now that this 5.7 is a pre-Vortec with a 2 barrel carb.
I was prepared to take a chance and drive out to thoroughly checkout the boat.
But I was really hoping it was a Vortec with a 4 barrel that I could enjoy rebuilding.
The rest of the boat looks pretty darn nice, especially the original upholstery.
If I had encountered soft floors or transom I would have passed on it anyway.

You are right to ,focus on the floors transom and stringers. The engine is easy if the structure is ok.
