needed original radiator shroud to fit 61 394 in a dynamic88.radistor measures approx.25" wide 17" high.or I think a round one may work as well.my fan is 18" across.thanks much bob.

 

I have a metal one removed from a 64 starfire 394 and a have the radiator too .

 

Rodbob, Was your car built with A/C or a special cooling option?
If not, then it will not have a shroud at all. And only a 3 core radiator.
If it was A/C or special cooling then it should have had a shroud and a 4 core radiator.
The parts book shows three different shrouds for 61-64 full size cars. #581424 for 1961, 583268 for 1962 and 587190 for 63-64.
Strangely enough, they only show two radiators for 61-64 full size cars. #3003445 for non A/C cars and 3155346 for A/C and special cooling cars.
If what you want is better cooling then you may want to consider installing Lunaboy's shroud and the 4 core together. Make sure you get the proper diameter fan to match the shroud.
