I do not know what vehicle that the 3.75" thick core came out of.  I hope 
Rusty has the answer.  I am also thinking the same way in that a properly 
designed duct will increase the efficiency of using the core instead of a 
thin radiator.  My duct will run from the landing brake back past the 
firewall about 3 feet.  It expands to the full width of the coolers.  The 
RVs are successful with their short ducts so I am wondering how small 
length X width or how thick is optimum when a longer duct is used.  Where 
in the strake are you locating it?   Are you building a Cozy?
