Default Front motor mount 1960

I'm going to replace the front cross brace motor mount. Here is the sequence I was going to use. If anyone sees a problem, please advise before I screw it up.
1) Support engine
2) Drain cooling system
3) Remove Fan & belt
4) remove generator support
5) remove water pump
6) remove engine cross bracket

I agree totally, especially if you have any HP mods. I got a built 355 in mine and I had to do this. Anytime I ran it hard the wp would start leaking, after I braced it no problems since. If you can't do it , find someone who can or send it me. I have a bare block setting here.

No, the new one does not have the extra supports welded on. I've read many posts concerning this very thing on the forum. My current mount does not have those and I have no leakage problems. The only reason I swapping it out is someone at some time modified the mount to accommodate the incorrect water pump to make it look somewhat like a 61' or the one shown in your picture only worse.
I don't think I have to worry about too much torque. Mine is the basic 230HP. You clock it through the quarter mile with a calendar.

Hey Bill.....did you ever make a template for those extentions? Looks like a worthwhile project before I go adding 100 hp to my 62.

O-k, get a pair of 3/8 "studs to ease alignment for reassembly. Makes the job much easier.

I did this.
This is not the engine in the 56. I used an engine I have on a stand for fitting and testing for clearance. The upper bolts are counter sunk flat head with an Allen head recess along with counter sunk star lock washers. Thus, the bolt heads are flush with the back side of the cross over mount.

I replace mine in my 60 230hp and I didn't remove any of that. I supported the engine, took out the bolts, pulled the supports, put in the new supports and ran the new bolts through and rebolted. I will admit that the passenger side was a challenge around the radiator hose to get a wrench on, but I persevered.

Default water pump

I want to pull the pump completely out anyway to get things cleaned up in there.

Has anyone completely removed the water pump related engine mount bracket and used custom side mount brackets.

We did that a number of times back in the day, especially when running big block or W series (348 or 409) engines

The steering column is in the way of doing that on the driver side. I wanted to do that with my new 383 but ran into this problem

We replaced the steering box when we did that as well.

Cars were not exactly "stock"

Whatever you do, use Permatex #2 on the gaskets. NOT RTV Silicone sealer.

Default Permatex

One post in the forum says use Permatex #3. What is the difference between #3 and #2?

Pop is correct it makes the job much easier using studs. I might that cut a slot in the end of the studs to make it easy to remove them with a screw driver.

If you happen to have any exhaust manifold studs laying around, those work fine, and they have a small diameter hex head (smaller than the stud diameter) so no need for a slot.
