stk fan shroud
for my '55 -
with a '59 312 in it, stock radiator.
the fan shroud I got from mid fifty fits up fine to the radiator, but is easily 6 inches or more too shallow to house the fan.
I could not find pix of stockers to see if
1. the shroud is too shallow
2. the fan shaft is short
3. it was never intended to cover the fan
Any stockers out there that can advise??

Re: stk fan shroud
I can't tell you exactly where your fan should be in your stock shroud. However, to be efficient what you want is for the fan to be placed so that the air that is drawn through the radiator comes out at a 45 degree angle from the back side of the shroud. This placement will result in the fan being partially outside the shroud. The fan is never supposed to be completely enclosed within the shroud. Just use whatever extension is necessary to get the air flowing out at a 45 degree angle and that will produce the best results...

Okay , but I doubt a 10" fan shaft is what was there before.
Anybody can share a pix?
Did not see the right shot in the Galleries

Okay I just grabbed the fan shaft off my junker truck's 239 and it is almost 6"total from base to fan mount.
Sure looks longer than what's on the 312.
Cant wait to fit it up.
Good info from all - I would have expected the fan to be fully inside the shroud, now I know to target 1/2 -2/3 blade depth
