Cheapest quickest way just run a smaller fan. I run 1 of these with 500hp motor, stock radiator never goes over 180.

I bought the new shroud from Summit.  NOPE !!!   STILL scrapes. 

I don't know if they will let me return it but it definitely will NOT work.

This is the fan shroud from HELL !!!

ok.... the fan on the left is one that i am using now.. don't recall size but i think it's a 19". it has about 1/2" clearance all around. my '73, 302 had exactly the same issue u have. with maybe 1/4" at bottom fan/shroud and 1" or more on top. i wanted to keep the older rubber style mounts but with '73 frame side sat to low. so i did exactly what rackem said and i got 71/72 lowers and worked.. the older style lowers are drop and bolt. everything is the same it just raised the engine up about 1/2".
it'll cost ya the 140 bucks but your headache will go away.
or like mentioned get some 1/2 plate and drill holes to mount and place under the 73 lowers.
on a side note... do u have a/c in car. the shroud u bought is it for your car.. if both answer are correct rackam (if he still has it) had a non a/c shroud for sale.

Helicopter,

Once again, the best solution to your problem is to replace the frame mounts with 71-72 mounts. I forget if you have a 73 hardtop or convertible. The 71-72  coupe/fastback frame mounts are plentiful, I must have seen a dozen of them at Carlisle.

Here is a picture comparing all frame mounts used from 71-73 for small block V8 coupe/fastback and convertibles. Also, the convertible frame mounts were used on all 1971 models with a 429ci big block engine. You can clearly see the height difference as well as the elimination of the tab from the 1973 version between them.

Back in the day we use to drill a hole in the non captive style of motor mount and put a 3/8" bolt with a nylock nut on it . You still have the rubber cushion but the bolt keeps the torque of the engine from tearing the rubber into. They would also use a section of chain to hold the right side of the engine down but not be rigid. Did this on all race cars or you were eating the radiators up all the time with the engine flopping around.


When a man is in the woods and talks and no women are there is he still wrong??

I’m trying to figure out which mounts I have. I’m pretty sure they are 73 mounts but I don’t know if they are vert or hard top. I have a 73 mach1 with 351c and automatic trans. The first pic is the mounts that came on the car when I took it apart (don’t mind the piece of rubber I just put it in there to take up space it needs rebuilt). The primered one is the replacement for one but as you can see the hole that bolts to the frame side is taller and it has a “R” stamped on the ear. Is the primered one the vert mount or could the other one be?

Look around on the primered mount, there is usually a Ford part # molded into the insulator. That one might be a Torino mount.

The first mount (not primered) with the short mounting bracket looks like the correct mount to me for a 73 convertible. Here are some close ups of my 73 vert mounts. From what I have seen they are commonly stamped with the number 665, but I have seen 663 and other numbers.
