Fan shroud measurements

[summitflier]

If you have a water pump/belt driven fan blade.. the shroud does seem to channel heat better. Also, it's a safety thing. Fingers and fan blades don't mix well.
I switched to elec fans this year. No shroud at all. There are "cages" of a sort around the fan blades for safety. But the biggest thing for me was the room. I don't see a depth measurement in post #1. But I would guess the depth on my old shroud to be about 6 or 7 inches. Now I can move my engine forward if I need to. Run a long water pump if I want. Even run serpentine belt drives if I want.

The distance from radiator to the fan blade mounting point on water pump is 7 1/4" and the distance from engine to fan blade mounting point also the water pump is 7" thinking w/p is a tall one. I will be using a original 6 bladed 18" fan that is 1 3/4" tall/deep/thick.

Shroud pictures that match your measurements.

Jason can you lay it flat on ground and give me a measurement for overall height, I think it'll be in the range of 6-7"tall

It sounds like your V8 engine is in the 6 cylinder frame hole locations giving you that much room between rad and water pump flange. Thats ok as it gives you more room to work with for fan setup.

On this site i was told if there isnt any room from the dist (mine a HEI Accel w/super coil) too fire wall (1/4" or 1/2") then engine is in I6 mount. But if there's more room 1" or so (mine has 1 & 1/4" space) then its in the V8 mount. Dont really know if what I was told is true or not, that thread I would have to dig a little bit to find the person that posted that.
