Patriot VS TTI VS Dougs

I just installed a set of Doug's on the 340 in my '74 Duster. Wow. Talk about a shoehorn fit. Now, granted, I have a Milodon road race pan and a 4 speed, but its tight. I went with Doug's because like the TTI's they do not pass under the center link, and they're good for about another 1/2" of ground clearance vs the TTI's.

I basically followed all the install instructions, I had to drop my center link, disconnect the steering coupler, drop the starter and raise the engine about 2" off the mounts. I suspect it was because of the road race pan, but I also dropped my steering box (manual). Once that was all done, the headers almost went in. Driver's side was ok, on the passenger side I also had to pull the rear exhaust stud and replace it with a bolt. That took care of putting the headers on. On the driver's side the steering box and starter have to go back in before you fully install the header.

I reworked the Z-bar, but that isn't that hard. It also has to be done like this for the TTI's. The arm that goes to the clutch fork just gets moved to the very end of the Z-bar and reversed so the stud for the clutch adjuster is on the inside. Then welded it back on. Reassembling is bit of a trick, that arm on the Z-bar travels in about a 1/2" wide space between the header and the starer. Might be less than that...

So, install was a PITA. But, the headers are about as tucked up under the car as they can be. And I didn't have to dimple anything, even with the Milodon pan, 1.12" torsion bars, and 4 speed linkage.
