My car is a 75 with a 2.0 four. Is there a light weight option for the engine mount bar? I'm trying to put my car on a diet and damn that thing is heavy.

I suppose you could spend thousands designing and fabricating a bar made of some exotic and very lightweight material, but weight that low is actually of less importance than weight elsewhere in the car.

The Cap'n

Mostly to keep your engine from dragging on the ground.

Yeah I know all that but it's cast iron. I would think a tubular mount could be just as strong and much lighter.

I think he may meant in compared to say a 911 engine bar. My guess is that it was a low-cost option (cheap to design and make).

At least it isn't made of reinforced concrete.

It lowers the CG of the car.
Its forged steel, much stronger for the application than cast iron.
Feel free to drill lots of holes in the web. I have one like that somewhere.

Sweet, thanks Chris. I have an extra one I'll use just for that.

Forged steel? I take back my comment about it being a low-cost option.

No kidding, I would have figured the bar to be cast, cheap and easy to produce.

They do seem heavy.

Looks like cast steel to me, not forged.

Haven't seen one in years but, IIRC, forged steel.
It pays to learn the visual difference between forgings & castings......like when someone is trying to sell you pistons.

I just havent looked at it lately.

Tubular mounts tend to have some spring to them, which doesn't help the rockin' and rollin' that the engine will do. On some Six conversions, the tubular mounts apparently flexed to the point where they fatigued and broke.

The stock side-shift motor mount bar does seem somewhat overengineered, though. You can take some weight out of it, but the weight is in pretty much the least harmful possible location, in the middle of the car and down very low. It would probably be better to take a quarter of that amount of weight off the top of the car, or half of it off of one end or the other.

I fab'ed this up several years ago just for fun. It raised my CG up several inches I'm sure.

Ury are you currently using that bar? If not how is your engine hung? I was waiting for your response.


Yeah im sure the center of gravity would be raised but only minimally. I don't think it would be that hard to Fab something up that's half the weight and just as strong.

Yes the bar is on my car now

Yeah I think im gonna have to make me one of those.
