These are just too small. The distributor is a Prestolite.

Post some larger pictures, and tell us what makes you think it is a GM
engine.

Give all casting numbers or part numbers you can see.

Are the rocker covers 4 bolt or 6?

A side view of the cylinder heads would help, as well as a front-on view
of the timing cover.

the 429/460 has valve covers about twice as wide as these and more than 4
bolts in them. These valve covers are small block chevy.

More/bigger pictures would help. The chryslers usually have a slant to
the distributor. Maybe it's the 429/460 ford block? 28 ft is big enough
that it could be some sort of big block. There is probably some casting
numbers on the intake and heads that might lead somewhere.

One thing is for sure, don't expect those old log exhaust manifolds to be
any good.

The Ford FE valve covers have more than 4 bolts. It's clear (despite the
puny photos) that these VC's have 4 bolts.

The layout is just like a 352 Ford, or 390/427/428 FE engines. If the
boat is older, this could be the case, but the rocker covers still look
too small for a 352.

Sure looks that way.

Did Grey Marine ever use Chevrolet heads on a proprietary block? This
would be the only way to get the distributor drive gear into the front
of the engine as I see it.

That distributor is right where they are on the FE blocks. I can't
think of any common wide block that shares bore spacing &/or bolt
patterns with the SBC.

Anyone?

The more I think about it the more I remember the intake was different
on the 460 as well.

Looks to me like a small block chevy reversed. Seeing your heads are
driled for bracketing on either end, it sems like the water pump is
running off of where the flywheel "ought" to be" deffinately doesn't
look like a typical chevy water pump, but some wierd thing on a wierd
casting instead of mount.

just a guess

It looks like a Graymarine Fireball 350 aka Buick wide block 350. UD

Looks like a smallblock chevy that is installed with the front of the engine
facing to the rear of the boat. The water pump and belts look like they are
mounted on the back of the engine and the drive shaft would be connected to
the front of the engine.

Imagine changing the timing chain on that mess.
