I bought an aluminum rad from C&R racing for $330 (that includes shipping).
AN 16 outlet and inlet, with a small air bleeder in one end.  It's 18"x25"x2
1/4" thick.  Quite a bit larger than required, but I don't think I'll have
any cooling problems if I get the ducting right.

Sounds good to me Brian.

Brian,
Why did you go with the AN 16 rather than the AN 20?  I noticed that CR sells AN male and female bungs that can be welded to the water pump inlet and outlets - is this how you plan to plumb your radiator?  Here are my most recent thoughts on radiator plumbing; AN 20 male outlets on the radiator, welded male AN 20 bungs on the water pump, and -20 Stratoflex hose and fittings.  Also, how do you plan to mount your oil cooler?  Mike Wills suggested mounting the stock oil cooler where the battery presently resides in the RV-4.  This would have a lot of advantages but I am a little nervous abount the structural changes that would be required in the bottom skin of the RV-4 as well as having high pressure oil lines behind the firewall (as Mike also pointed out).  I will probably keep the oil cooler under the cowl.
