Anybody know anything about these engines? Anything special about them? Thanks!

Never seen anything quite like that. Tommy'd be the one who'd know, But with the Center riser exhaust, Motorsport style Valve covers, might be a little more than your average marine 460. :thumbup:
But probably not, who knows? Casting numbers might help a BIT, but prolly a d1ve (block), d3ve a2a (Head) combo (Std marine engines mostly had these I think) So unless a hotter cam, more compression was added, you know where it's going, lol.
Regardless, you probably have a standard Hardin Marine 320HP 460. Still a stout engine, and can be hot rodded quite a bit with bolt on parts before you need to remove the engine and go inside it.
Did I mention it looked CLEAN? Dirty that pig up a bit would ya? Making us all look bad here.............. >:D

It looks like the standard issue glastron carlson setup.
The cast iron intake was a cobra jet. Nice big ports feeding junk small port heads.
Pedistal mount cheapie rockers, mild hyd. cam and lifters.
Oil pan was a front sump 6 quart with a baffle. again from the cobra jet.
Dual point dist.
Dish pistons.
In reality, a nice dependable medium 320 HP engine.
No, nothing special

Fordbuilt their 460 Marine engines to a slightly different spec than their 460 passenger car/light truck engnes. For example:
The typical Marine 460 that came in the thousands of boats came with front sump Cobra Jet oil pans (has windage tray) , passenger car dished cast pistons (the mid-1980's 460 King Cobra had TRW forged flat tops), the heads were usually non-thermactor D3VE's with different valve springs, retainers, and the addition of spring cups, heavy duty truck rods (essentially Cobra Jet rods), the Super Cobra Jet intake with a post-70 date code, Super Cobra jet camshaft, and usually fully grooved main bearings.
