Motor Mount Bracket ?'s

[Iron Ranger]

I have this conversion bracket system from allstar performance(I think), but the plates seem too thick for the motor mount stud to fit through with enough thread.

The other similar brackets that I have looked up says that their plates are
1/4'' plate, mine's 1/2''. Here's some pics:

also, how would these bolt on, and which one is driver's side and which one is passenger side?

Take em to a machineshop and let em counter bore the stud holes where you can get a full nut on the stud. And use a washer headed nut with lock knurling on the washer face. Then when you install em, use locktite on the threads as added insurance.

I was just going to do one of two things:

1. Let the machine shop at work mill down the mounting surface from 1/2" to 3/8"

2. Cut the 2 apart and weld a new one on with either 5/16" or 3/8" plate

ahhh, I have the same kit I think. I haven't gotten to the install yet, but I was wondering the same thing. I hope someone can help you (and me!) out.

Yeah, in the v8 conversion library, the guy said that the mounts can be made with 1/4" steel.

Now I am not judging him, but I think that 3/8" plate would work a lot better. The offset of the motor to the frame rail, plus the torque of the motor itself might flex the 1/4'' plate a little too much, but 3/8" should work a lot better.

I'm going to make one out of 3/8" in the next few days and see how it goes.

The design of the plates in the Tech Library work very well with 4.0L (V6) engine mounts. I began with that design, then adapted it to suit my desires. The 4.0L engine mounts bolt to the cradle like they were designed for it, because -- they were. I don't want to get argumentative -- I understand the 3/8" rationalization -- but, 1/4" is fine.




One of my favored threads on 4.0L mounts with adapter plates.

But I got a 2.3 in my rig, and I already have the necessary mounts.

At my work, we have a $600,000 CNC Plasma Cutter that can cut my pieces to any dimension I need, so I'll just use the 3/8.

I have a knack for overbuilding things, so 1/4 would work, but I feel better using the 3/8

I'm not sure what you mean by that. I hope you "already have" the 4.0L mounts waiting for the adapter plates to be made. IF by "already have", you mean the 2.3L mounts -- don't do it. The 2.3L mounts won't handle the load or stress. They are hydraulic, if memory serves me correctly.

Nah, I meant that I made new plates out of 3/8" plate. It looks exactly like the conversion plates in the first thread, but using 3/8" plate.

Use my 2.3 mounts? I didn't even trust the 2.3 on those mounts! Very squishy design
