Frame mounts and engine mounts are big block Chris Alston

There's a lot of things about your car that aren't stock. The steering box is bigger in the area of that tube as was pointed out, and the raised ports pull the headers up and out, probably not helping either. I am not sure about the Chassisworks mounts as being exact copies of GM big block mounts, so that may or may not be an issue. Is the passenger side frame mount taller? Can't tell for sure. If you look at the pic in the link I left in post #2 you'll see the drivers side is noticeably taller than the passenger side. Your pic doesn't look like that much of a difference, actually looks like the same height. If the engine is raised on the drivers side it takes the tube off the steering box, or at least lessens it. It also pulls the passenger side away from the idler arm.

If SW was told about the raised posts, to me that's a big part of the problems on the drivers side. The passenger side with the idler issue, don't think being a little lower and closer (non-raised ports) would clear the boot. I'm still thinking those frame pads are wrong.

How much vertical clearance do you have in the fire wall and tunnel area?

I once tried to explain hot rodding as a series of "stack up errors"... a little here - a little there and no you've got to hot rod about 6 parts to make one of them work...

I always appreciate the efforts of factory (OEM) engineers more - after building a hot rod...

If you have the room have a custom set of frame pads made. It will be cheaper than modifing those headers or swapping out to a rack kit.

Thanks for the idea Vince.
The problem is i have a custom flat firewall and i have built it around the height of the engine as it is now and with the mounts i have.
The car is in the exhaust shop now getting the headers cut up and made to fit i just have to suck it up and open my wallet and move on from a bad experience.
