Lowering motor mounts

[snailmont5oh]

If this question has been asked and answered, you have my sincere apologies.

I have a problem. Here's the long version.

I have a '79 Fairmont, 2-door sedan that came factory with a 302 and a 4-speed. I'm not currently using it, but that's where the story starts. The motor mounts let the engine sit so low in the car that the oil pan rubbed the steering rack, and the Hooker Super Competition (equal length shorty) headers hit the steering shaft. I thought they were worn out, so I replaced them. Same deal. I drove it that way until the day that the assist cylinder ruptured on the autocross course. Imagine the excitement involved with losing steering boost at exactly the same moment that the rear tires get oiled. Fun stuff. So, I bought a pair of Prothane poly mounts. They raised the engine about 1 1/2 inches or so. Since then, I've had a vibration.

Also since then, I broke the frame on the '79, which made me notice how much it needs a full restoration (read: piece of shit). I took it off the road, and was lucky enough to find an '80 boxtop 'Mont that is freakin' pristine underneath. So, I took all of the good stuff (engine, trans, rear, suspension) out of the '79 and put it in the '80. A friend offered me the K-member from a '90 5.0, so I installed it to get a better caster angle.

Well, my driveline vibration is freakin' horrible now. I started looking into stuff, and I found that my transmission and my pinion shaft both point at the ground. Not good. I know that I need to work with the pinion angle some, but I would like to lower my engine about and inch and a quarter, to a) help with the vibration; and, b)get the engine weight just a little lower in the car for better handling. I know, it ain't that much, but every little bit helps, right?

So, the question is this: Does anyone know of a poly motor mount that will lower the engine somewhere between an inch and an inch and a quarter? If not poly, how 'bout solid? Do I have to make them? Any other thoughts on the subject?

Thanks for the help.

Later,
Mike.

No direct experience (what's a V8?) but here is some info ...

I have HPM 3/4" drop mounts, inatke cleared much better with them over ES polys.

I'm running poly and my vibration is fine.

If vibration is bad now.... don't consider going to solid mounts.

I think your vibration is caused by something other than engine mounts.

I think you're absolutely right. I think my vibration is caused by improper driveline angles, and lowering the engine (via motor mounts) will help the angle problem.

go solids i did and love them well not really ,but the engine doesn't move

I've read Energy Suspension motor mounts are not as thick as Prothane mounts.

I gather it's something like an inch lower, but that's just what I read.

If that's the case, it would be pretty much exactly what I need.

Update:

A fella at Maximum Motorsports tells me that the Prothane mounts will raise the engine a lot, and that the Energy Suspension mounts won't.

Looks like I'm in the market for some Energy Suspension mounts.

Thanks for all the help.
