See if you can have Marc take a long drive with you and fine tune the chip. There is a Dyno in BG and they will let you rent time. may as well make the best of it. There is nothing like a very well tuned car.

Thanks Frank, seems that would be asking a lot of Marc?

Headers are rubbing just a bit on the stearing shaft. Looks like its just kind of shining up the shaft. Is it a thin tube, like I might cut it in half, or is it a solid piece of stock? The White lightning ceramic coating is pretty rough to the touch.

Problem could be......The drivetrain is off center. Mine was off center and the monkey's that worked on it at that time knotched the header.
There is another post on here about centering the driveline. Maybe a search will find it.

Steve,
This is a guess, but I'll bet that shaft is fairly thick walled if it is hollow; I'll give you even money it's a solid shaft though.

I suppose you could remove the shaft and weigh it - should give you a pretty good idea whether it is solid or hollow. But! I appreciate what Frank is saying re driveline centering.

If you loosened the nuts on the motor mount studs and the rear C-beam bolts at the differential and took a pry bar, I wonder if you couldn't move the motor over - even 1/8" might be all you'd need to clear the shaft (before cinching up the motor mount bolts). You might have to place a jack under the motor to just free the mounts from their rests - just enough so the mounts will not stick in place and simply flex when you pry on the motor.

Prying would be worth a try, and heck of a lot easier that removing and grinding the steering rod, methinks...

Thanks guys. I gotta buy a lift, I hate not being able to get under my car. But that's $2,500 that won't buy me upgrades. When the headers were first in, we could see daylight. Not much, but it wasn't rubbing. Must be from when the engine torques then settles back in. It gets twisted frequently.

Time for new motor mounts possibly from your description of the issue? I'm sorry that I'm good at spending other people's money, or something is loose like C-beam bolts or motor mount bolts?
