Rich,
I have a similar problem with my Barracuda (with a Max Wedge)...
with the hood off it ran cool as a cucumber but with the hood on the temp
would creep. If I drove it long enough, it would run right up to 230+ by
the time I'd panic and shut it off or pull the hood. It seemed like there
was plenty of air coming in (we did the paper test as well). We also
wondered about the hood scoop pressurizing the engine compartment, causing
lack of air flow through the radiator. An air plenum sealing the carbs to
the hood didn't help, so we ruled that out.
Along the way we also tried 3 different high volume water pumps, a
different housing, various thermostats, and even an electric water pump
and
cooling fan, all with similar results. The fan shroud seemed to help, but
at this point we've concluded that the problem was getting the hot air out
of the engine compartment.
Thinking about it, you have a 4 square foot hole in the front of the
car (the radiator opening) with a fan to pull the air through it when air
isn't being forced through it going down the road. Looking around the
rest
of the engine compartment, I'm not seeing nearly that much room to allow
the
air out - removing the hood apparently creates the needed space to
evacuate
the hot air pulled through the radiator.
BTW, the smaller crank pulley slows the water pump down, so you may
want to stick with the larger one... that's one of the changes we're
making
this year - a larger stock size pulley to replace the "trick" small
aluminum
piece.
As usual, my $.02...

I don't really have any room in that area on my car. The horns take up one
side and my radiator is wider than the old one. The batt box is in the way
too. Multi holes is probably fine. I have thought about removing the misc
access plates along the inner fender area, etc.. I ran without them for
quite awhile and decided to put them back in. I think some ducts under the
front bumper directing air back and up would be good too.
I still would like to do a fan shroud and a smaller pulley. Although I
stuck
a sheet of paper near the front of the radiator and it sucked it up to the
radiator at idle. There is air movement.

Great news and still issues...but u have made headway Rich!
We talked about more air to the eng compartment. After studying the
situation....what u think of this? I want to go to Lowes and get the
biggest bit I can for my 1/2 drill and make the radiator support
shield look like swiss cheese directly behind the grill. I am open for
your thoughts?
