Anyone built or found a fan shroud to fit champion radiator??????

im using the 26" with a big block, i think with the engine offset and hieght of the BB, ther eprobably isnt a factory shroud that would work. i very rarely have problems with the temp but when it does creep up its in stop and go, a shroud would help for sure. i was thinking of either aluminum or fiberglass, ive worked with fiberglass making speaker enclosures before and had good results, i never saw that link though. very helpful to see it done.
