70 Dart TTI header install problems #136541 10/14/08 09:30 PM 10/14/08 09:30 PM

6PAX OP master Joined: Jan 2003 Posts: 5,621 Detroit area	Over the weekend I installed a new set of TTI headers on my 70 340 Dart. I had to have a spacer plate made for the driver side motor mount to lift up the motor a bit as the third header tube back was resting on the power steering box. Today I discovered that the steering center link rubs on one of the driver side header tubes when the wheel is turned to the left. I thought TTI headers were supposed to fit like a glove but not on my car they don't. Anyway, does anyone have a suggestion on how to get more clearance on the center link to avoid having the rubbing issue? The only thing I have changed is the car had manual steering and I installed power steering. The power steering box and pump were from a 70 318 Dart.

Make sure the mounts are on the correct side of the block,also the drag link isn't flipped around.

I'm pretty sure the motor mount brackets are on the correct side of the mounts on the block. Should the brackets attach in front of or behind the mounts coming off of the block? Also, I had been wondering if it was possible that the drag link is reversed but I wasn't sure if it would bolt up if it was. Will it fit properly if it is reversed?

The motor mounts are fairly new as is the trans. mount.

Even after adding a 3/16" shim on the driver side the header tube still makes contact with the steering box. The only things I can think of to solve this is to either shim some more but I don't know how much I can shim without creating other problems, dent the header tube which I would rather not do or grind off the edge of the steering box to make clearance which would be a lot of work. I was also thinking of possibly using different motor mounts. The ones one the car are fairly new but only measure 7/8" thick with the motor sitting on them. My friend has Schumacher mounts on his car that are a little over an inch thick under load. According to Mancini's the correct thickness is 7/8" but maybe a thicker mount will solve the problem? Your thoughts please.

Have you ran across anything in the instructions along those lines? I have a set of TTI's, but have not put the car back together yet (paint job) to know all the details.

I used Schumacher headers and mounts on my 440 Swinger with PS and was determined not to ding the headers. It was a real pain but I ground off part of the steering box to gain about 1/16 clearance. The headers have no dings anywhere. I also used the Schumacher torque strap to keep movement to a minimum. Take your time and do your clearancing now not later. It will work just fine with a little effort. Russ:) BigBlock 74 Swinger

I too thought these were to fit like a glove? One reason for the big $$$. Mr.Runum 69 RoadRunner 383 4spd coupe, 06 Hemi Daytona Charger, 08 6.7 RAM QC short bed 3/4 4X4

Initially there was still contact with the steering box but after tipping the driver side of the motor up a little on the motor mount pads I have about 3'16 to 1/4" of clearance with the steering box. However, the drag link is still rubbing one of the headers tubes when turning the wheels to the left. It seems like the rear of the motor needs to be lifted. I'm thinking about shimming the trans. mount to see if that solves the problem. The k-frame looks to be a correct 67-72 style frame. I just don't understand what could be behind all of these problems.

Mine hit the tubes terribly when the suspension was unloaded, but, when on the ground, no rubbing on steering gear. There are some other issues I had, that's another thread...

I have installed TT1 standard head headers on my 70 Duster, and 1 7/8 w5 headers with no issues with either set. I use solid "stock style" motor mounts, and a factory tranny mount, and have a manual steering box an zero issues with either set of headers. sounds like your motor/tranny arent sitting in the factory location. 69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight 418 BPE factory replacement headed stroker, 565 lift solid cam Best so far, 10.40 @127 1/4 1.41 best 60 foot 6.60 at 103.90 1/8

Quote: Sounds like something isnt "stock" in your motor placement. I considered that but if something isn't stock I don't know what it is. Everything looks as it should as far as I (and a couple of friends) can tell.
