Would something like this help?

Brake lines? Looks to me those things are too close to the frame. What chassis is that?

'67 Lemans. The left manifold is only about 1/8" away from the frame. I have about 1/2" of clearance on the right side. The 326 fit in there better, but it had the log manifolds. Would changing the motor mounts help that? I used the same ones that were on the 326 since they looked to be in good condition.

Come to think of it, when I striped the front end down, I remember that my motor mount plates (part that bolts to the frame) were different sizes. The plate on the driver's side was only about 1 1/2" tall. The plate on the passenger side was about 2 1/2" tall. I just figured that this is how they did it, and didn't think much of it, but could this be why I don't have any clearance on the driver's side? Are the mounting plates supposed to be like this??? They look stock, but I don't get why one would be taller than the other -- especially since the motor mounts themselves bolt up to the engine at the same height on the block.

Do the valve covers seem to be at the same height? Like is the engine level in the bay? I'm not that familiar with 66-67s, so I can't say for sure on the frame mounts. Someone else will chime in though, I'm sure.

I probably would have replaced the rubber mounts regardless if they looked good or not. Figure might as well if you're in there.

Also, aren't the f-body and the a-body manifolds different? That might make the difference you're seeing. You have part numbers for the manifolds you have in there?

Yeah, the engine sits about perfect other than that left manifold being too close to the frame. You're correct, there are different RA exhaust manifolds for Firebirds and GTOs. Mine are the correct part though. Appreciate all the help!

The mount is taller on the drivers side.
