I can't imagine that would last long without some kind of cooling. He
may have tricked up some kind of radiator but I would be curious how
you recover the water. Outboards discharge directly into the exhaust
manifold. I suppose you could make up a different flange right at the
block to divert the water.,

The block is filled most likely.http://www.jegs.com/p/Moroso/Moroso-...45552/10002/-1

A drag motor does not run very long at a time. *5-11 seconds for the 1/4 and
20-30 seconds in the staging area.

True Bill, but with the engines mdified for a racing design, extreme
RPM's and a mixture of lord knows what kind of fuels, drag engines
develop a lot of heat very quickly. I would imagine that after a few
runs or so the engines were just about junk.
