fan shroud
#1
Hi All

Long ago, the fan shroud was removed because the fan scraped the lower part of the shroud.
With the restoration, I have new engine mounts, radiator, shroud clips,  thinking that would solve the problem----NO !!!!
I "adjusted" the engine mounts to highest position and it still scraped the lower fan shroud.

Any ideas what I am doing wrong?

Roy,
what model year and what year mounts and perches ?
Some say that engine will sit 1'' lower if 1973 motor mounts and perches are used.
that could also mean that there could be a difference in shrouds between model years.
Just thinking out loud.

Assuming you have the correct engine frame mounts for your engine mounts. ie the lower 73 frame mounts paired with the taller 73 engine mounts or 71-72 frame mounts with the same 71-72 engine mounts. 73 mouth are not reproduced. If you use repro 71-72 engine mount on 73 car you need to replace the 73 frame mounts with 71-72 year frame mounts.

with that said, alao check your transmission mount position. The position of the trans up or down can tilt the front of the engine down or up. Sounds like your trans could be sitting g higher up in the tunnel tilting the engine down in front.

I ordered 73 mounts. It very well could be the problem.

Good Idea.  I got a transmission mount piece with the engine mount set but did not install it (I didn't think it would be necessary).  Maybe I should take a look .
Thank you

The 73 motor mounts are called captive mounts and were designed to meet new federal regulation that year. They are taller. Too compensate for the taller mount Ford lowered the frame mount/perch. See the two versions of the perches in the pic below. There was no meaningful change made to the shroud between the years.

Hmmmm.

I have a 71 that was an 11/70 build and I changed the motor mounts and perches to the 73 captive style.  Shroud in place during break-in and I had no rubbing problems at the shroud.

helicopter , what mounts did u have on the engine side ??????? rackerm is right on the money and helped me figure out my issue.. with that said wondering if u had regular rubber style on the motor side??? if so bingo.. that was exactly why my motor was sitting low. i changed frame/engine mounts to '71-72 and it solved my problem. the '73 frame side is about 1/2 or so lower and if u found regular rubber mounts on engine is will sit lower and hit the shourd .

Today I replaced the Transmission mount that came with the new engine mounts.  Results: Negative.  Still scrapes.

I called the supplier and they are sure the 71 to 73 engine mounts are the same.

Then why are the fan blades still hitting the bottom of the shroud ?

It HAS to be the mounts !!

Please don't take my word for it cause I don't know this for sure but it seems to me i read somewhere that there's not only a difference between 71/2 and 73 mounts and perches but also between convertibles and fastbacks or coupes.
Can anyone confirm or disprove of this?
I know I've ordered engine mounts for mine twice and both times they were wrong. (I just don't remember if they were tall or small)
