small block A/c clutch fan??
 

Does anyone know what a 72 small block is suppose to have for a fan. Size, how many blades, clutch and if there is a spacer how deep is it. Also what differences is there with a Fan shroud with a/c compared to a non a/c. Any pics of a big block fan shroud for another one. Thanks

Just measured mine at 18" with 7 blades. Can't recall if there's a spacer (I don't think so), but from the front of the engine block to the fan mounting bolts is ~ 5 1/2". Hope this helps.....

Anyone know if there is a spacer and how long it is if there is one. Any info on the shrouds
