ok i jsut put QTP LTs in. looking under the hood on the passanger side you can see that one of the primaries is about 1/8" away from the k member. How can i keep it from touching that. i am not too sure but it might alos be touching the stering link too.. Also there is a little vibration at certain RPMs..does anyone else have this problem too?

any help would be greatly appreciated!

Yeah, mine bangs/vibrate but not alot. Sounds like I need poly motor mounts.

I had mine bent with the same problem.

If your motor mounts have some mileage on them or some wear, the motor is moving more than it should. If you have 1/8" of clearance and it still rubs, the motor mounts are shot.

Mine doesn't hit the steering knuckle but it's hitting on the firewall or the floor board. I'll do some investigating tomorrow.

Bene, mine is not hitting the stering linkage, it is about and 1/8" away from it. Also it is 1/8 from pasasnger side k member.. i pounded the floor board in.. What i am really concerned about is the mother fvking vibration.. it is slgiht in at any RPM but very noticable at 2400 RPMs what the hell gives?????? i think i need to get it on a drive on lift with the motor running and see what is happening..

any other ideas?

I'm getting some vibration too man after my header install. Mine seems to be only when I'm taking off in the lower RPM arears. I'm going to double check a few things this weekend.

Mine is sitting against the fuel line cover bolts. Its waaaay too tuck in. I have to some massaging on the firewall and do some adjustments on that area. That's the only thing I can see thats hitting.

wow im jealous.. i wish my headers were coated they look like ****! mine hits the k-member every now and then and i think im going to just shave it down a bit.. the real problem is the floorboard.. my headers/y-pipe rattle the **** out of my floor

There are quite a few writeups on this particular subject. It could be that the headers are out of spec (they didn't bend them quite right). This happens and seems to be a common problem.

More than likely though, it's the motor mounts. If you go with LT's, you almost always need poly motor mounts.

I don't know exactly what GM did, but the material they used for the mounts SUX! The motors really bounce around and move in the engine compartment....some much more than others. There's too much travel in the motor and not enough clearance with the headers....simple (but PITA solution).
