I want to thank everyone for looking over my engine installation and I will
try to address the comments.

"It looks like the hot cross tube is awful close to the radiator.
 Besides blocking flow, it will radiate a lot of heat back into the
 cooling system.  Have you done enough high power engine running to know
if it's going to cool OK?"

My cross tube is fitted with a SS. heat shield.  The clearance between the shield
and the radiator is 1.5 inches.   The last attached picture is a frontal top view
shows the cross tube and heat shield only cover about 3.5 inches of the corner
of the radiator.  Do you think I will still have problems with radiant heat into the radiator?
I can add another thin shield and/or connect a blast tube into the space between the heat shield
and the cross tube.

My calculations indicate the air exiting the radiators should be maximum  velocity of
about 40 ft/sec - based on inlet area and radiator area at 200 mph..

I have run the engine several times at full power with the cowl on.  It appears that the
temperatures were stabilizing between 185 and 195 F.  I really need more full power
run time to check it all out!

Mark S. suggested i support  the aluminum tube connecting my 2 fuel rails.
I will add a clamp there and look at the other fuel lines at the pressure regulator to see if
additional support is needed.

Again - thanks everyone!
