Anyway, back to the Sierra. Here is some pictures of the headers. They are a tri-Y design, the
inside dia. of the first parts is 38.4 mm ( 1.51" ). The next part will be around 1.75", I don't have
those parts, so I can't say for certain yet.
Both headers must clear the chassis rails, as the headers have to be on the engine when I
hoist that up from below. That is the only way to get the engine and gearbox in place on the
Sierra 4x4, as the crossmember have to be on the engine when it's installed.
Be gentle on me please, this is the first TIG welding I have ever done, the guy welding for me
decided to throw me to the wolves ( "Time for you to learn to tig...") so I think It's better to
get all the mistakes over and done with here instead of doing them later on the turbo headers....
