Default prop test engine- cheap

What have folks found to be the cheapest engine to swing a prop for
function and reliability testing? Needs about 100 hp at 2500rpm with
maybe a little extra up to 2800rpm. I would rather not go direct drive
if I can help it but that might be the cheapest way.

I thought about jacking my truck up and using a shaft off of the
driveline in some sort of big steel fixture. Now that would be
interesting. Heck, I could make a barge for my truck and "drive" it
around the lake like a big airboat

Seriously though, what's the cheapest option out there?

How about a junkyard motor?

If you want to test a prop, for reliability, you must test it with that sort
of engine it is supposed to be on, for vibration reasons.

Yes, it will definitely get tested later on the correct engine. I want
to do an initial run to veryify a few things first though.

What 100hp junk-yard engine could be readily adapted to a prop but not
have nasty torsional issues?
