ZZ4 radiator shroud
Does anyone know which radiator shroud will work on a 72 with a ZZ4 engine? The stock 350 shroud is just slightly too small in diameter. The big block one does not seem to fit correctly (the diameter is fine).

Re: ZZ4 radiator shroud
You need an 18" diameter fan to fit the factory shroud. If you are running a serpentine belt you need reverse rotation fan. I used a Derale 17918 fan (steel, 6 blade, reverse rotation, 18") mounted to fan clutch Car Quest part # 215168 to fit 30mm x 1.25 threads on the water pump hub.
