'70 Duster Revival: Drag Racing Heart | Pro Touring Soul
At the 2012 Mopar's in the Park I picked up a set of new 1 7/8" TTI headers from Mancini Racing. (Polished ceramic coating with the thermal barrier.) Absolutely gorgeous!
In an effort to make sure everything fit as it should when the car was finally painted, we dry fit the entire front end assembly. The engine was mounted and then we installed the headers and the torsion bars.
Glad we did this because we found that the header clearance on the driver's side was very minimal. Any movement of the motor when running would cause the slip tube header to rub on the frame rails. Something had to be done.
To remedy the clearance issue we traced around the header and onto the frame rail with a paint pen. Next, using the markings, the frame was notched with a cutoff wheel. A chunk of 3" pipe was cut and then tack welded it into the notched area. After some final trimming the piece was final welded and the excess ground smooth.
