How difficult would it be to put the "cold" water into the engine
at the center, and remove it at the ends? Or, vice versa?

Would this also help out with the spark plugs?

What is the max temp for the plugs (so that you don't cause some
type of failure at the plug holes and or with the plugs themselves)?

Larry Childs is doing it this way on his upcoming aluminium end housings.

He is fully aware of the spark plug cooling problems.

As an interim solution in case Larry does not get his parallel
cooling system perfected this would help. He is a busy man
and he has a biz to run. I know how that goes.

All this does is simplify the front end housing by removing all the oil
pump plumbing and rotating the front main bearing oil gallery
to get it out of the way of the water passages to the
lower spark plugs. Notice the tension bolts are not screwed into
the front cover. Nuts are used instead.


All the oil plumbing and
the oil pump are replaced by the off the shelf dry sump pump.


Same as done on the time to climb engine. The water pump
is a sprint car part but it is not optimum as it has two outlets
for a V8. I am still looking for a better pump. We could NC machine
a single  out let housing if necessary.

Ford has a Nascar pump. There is the pump and the housing that bolts to the V8 block. Use the pump but not the housing. Available through the FRPP catalogue. Did you get the email about strategic cooling that Stewart Components or Systems writes about?

Which one of these are you refereeing too.? What does the back side look like?

Yes on the email.
