Ok, I got some brand new BBK equal lenth shorties for my '91 5.0. Everything went great until I cranked her up. I could hear and feel vibration coming from the floorpan. Come to find out the headers barely touch the steering shaft. Anybody ever had this problem? Advise please! Should I just send them back? If the motor was raised like a quarter inch they wouldn't touch.

We had the same problem with my buddys MAC headers. Although his were longtubes and rubbed really bad near the steering sahft U-joint.

I would first try to bang out a tiny groove or notch. That might work. Good luck.

check your motor mounts. Over time they can wear and let the engine settle some. Lots of guys have fixed the rubbing issue by replacing the mounts.

I have the same problem with mine and my motor mounts are new. Most people just grind down the shaft a little or make a small dent in the headers as mentioned above. That's the only fix pretty much.

Does anybody know if they make adjustable motor mounts or kits or spacers?

You could replace your rag joint steering shaft with a newer, needle bearing u-joint type which is a lot smaller in diameter at that location.

I think I will try a metal plate spacer drilled out where the bolt goes on the motor mount or a thick washer. If this dosent work I may consider sending them back in favor of some long tubes and a short h pipe. Has anyone used BBK's long tubes? Any issues with fittment or rubbing? Thanks.

This is an old thread but just for reference I have mac long tubes and I can slip a piece of paper between the steering shaft and one of the tubes, you may get a little relief by loosening the steering column under the dash and moving it, they don't move much but it may help. Or you can ding the header pipe.
