Why fight it? If it is a donor motor.... center punch the head of the
bolt head and carefully drill it out with a drill a few thousandths
smaller than the size of the bolt threads.

Once the head is off... you can probably remove the remainder of the
bolt with a stud extractor, anyway....

Id rather not make the donor motor 100% donor motor. It ran the last
time I checked it (a few years ago now) and my goal is to get it up and
running too (why, tho, I'm not sure) on a boat of it's own.

I say again.... Once the head is off... you can probably remove the
remainder of the bolt with a stud extractor, anyway....

with over thirty years experience in machine shop I can assure you
that your approach to removal with lock grip pliers and other
implements of destruction will only yield.... well..... JUST a donor
motor...

BlazerFanDan.......take a minute to read Gene's credentials listed on his
homepage.........pretty impressive. When Gene speaks on matter relating to
machining and tooling everyone stops and listens. ;-)

Heat the block around the bolt and hammer on the head. Not so much
hammering that you damage it but enough to break loose the rust some.
If you have to dril it out start with a small bit and try to get as
exactly in the middle and drill as straight as possible. Then work up
the drill bits sizes.

I'm surprised nobody has mentioned an impact wrench. Pneumatic is nice,
but not necessary. There are manual impact wrenches.

Wouldn't do any good on a bolt with a rounded off head as he has
described.
