I got a set of TTI headers for my small block swinger. It will be going on the dyno shortly and wanted to use the TTI's during the test. Would it be wise to use a different set or will I be able to install the headers with the slip tube welded up?
 
you don't need to weld your TTI's. If it is a fresh engine, they recommend you not to use them during break in. however, I have.
 
Depends on the coating they may or may not have also, because dyno running with your new headers can burn the crap out of them.
It is actually recommended to use the dyno owners headers for break in and test pulls because of this.

There is no need to weld the slip joint
 
You WILL NOT get the headers installed with the torsion bar in place if you weld the slip tube.

DON'T DO IT!!!

The warning is for the guys that refuse to give engines the timing they need when breaking in. If you do it properly, the coating will not be affected by the break in period. Have broken in a bunch of cars with coated headers, never an issue.
 
Just started engine Saturday with new TTi headers.....once engine is fire and I adjusted idle speed up....I had a timing light already hooked up....set timing to 34 degrees....

coating looks beautiful....never even smoked during the run up
 
roller lifters or flat? use a little high temp silicone on the slip fit, and let it dry. I would not use new coated headers on a flat tappet break in, even with timing advanced. what if fuel/air is off?
 
You may want to check with the dyno operator. Some shops have headers with EGT probes and O2 bungs to help with fuel and timing adjustments.

Did not see ya in the garage with me...so how do you know what i was breaking in...yes...that cam and engine has run before...But even with a used cam..I start the motor and let it run just like If I was breaking in a new camshaft....and yes...it is a flat tappet cam....you can go see the video in our 71 Dart 410 thread...it only shows 40 seconds but you can see me adjusting the idle up to 2500 rpm..and setting the timing with in a few seconds of the engine firing...
 
Apparently I didn’t understand what a slip joint was. I thought welding was required or else you would have a major leak. My mistake.
 
certain brands of header use slip joints to make the installation of the headers easier....if there is such a thing.....I use the hooker 5204 on a few cars...and each side the 1st tube slips on....most race headers will have multiple slip tubes.....TTi use a slip joint on no. 7...to help clear the torsion bar on driver side.

100% FACT^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It's amazing how many people don't know how to set timing on a new engine, or even remove the distributor and the installing it.

If you had to start a magneto fired engine, you'd learn very quickly how to properly install a distributor.
