I'm going to fab up a fan shroud for my 65 F85 cutlass. AC car. It will be a rectangle to round. My questions are how much clearance on the round to the fan, and should I try to cover the fan blades completely, or just go half way? I read somewhere not to completely cover. Would appreciate any input. Thanks!

 

The radial clearance needs to allow for engine movement. Here's one suggested set of guidelines.

 

heres one to compare , or purchase

Thanks Joe, I will be going with the 1" clearance all around on the fan.

 

Thanks Stan, I am using that plastic shroud as reference.

 

if you want to go oem i have a metal round one available.
