You might squeak 125 out of one.

I have no idea how many HP it had, but it wasn't floored.

I bought it from an engineer on Guam who had never driven it over 35 MPH. This was before I knew about Amsoil, so I bought a lesser carb and engine cleaner to get the carbon out of it.

I made the mistake of shutting it off and carbon chunks stuck the exhaust valves open.

When I tore it down I found flat top pistons.

Cleaned it up, ported and polished it, cced the head, balanced the pistons and connecting rods.

Later, when I replaced the clutch, I found it had a 6 bolt crank.

I balanced the carbs for air flow.
