First off a 67 GT350 did not use headers but instead it used the factory hipo exhaust manifolds. With that said count on using the PS drop bracket if you plan on using any tri y headers like used on 65/66 GT350. Also the stock 289/302 Z bar will typically work better with headers compared to the rare and hard to find 67/68 Hipo Z bar.

  My experience with tri-y's:  No matter what, you'll need to heat and flatten a pipe or two.  So, fit them on the car before you send then out for any coatings.

Good advice, however if the tri-y headers are made correctly you don't need to flatten any pipes.

I don't know if mine will fit a 67 GT350 with power steering, never tried them on that application.  Just 65/66 Shelby GT-350.

Just an FYI for anyone using a Lakewood blowproof bellhousing with tri-y headers. The bellhousing flange on the passenger side will need ground for clearance as the header angles towards the center of the car. I also had to clearance at the adjustable clutch release rod as a stock rod will not last if using a HD clutch. I made a 1/2" diameter clutch rod and heat tempered it, as the original rod bent the first time I pressed the clutch. Suggest mocking up everything before installing in the car if all possible.

Scott, the 65/66 Try- y's will fit in a 67-70 chassis but you have to use the PS ram drop bracket for the PS ram to clear the header tubes.
