Good to hear from you. colder than a bear’s … up your
way, huh? but, I suspect that the Taj mahal you built in
which to do pipe magic is warmed.
I think Andrew markets headers with the necessary shape to
clear XJ platforms. Not all do that as I hear.
I like tuber headers. My jeep has an OEM version to get the
last bit of oomph from it’s historic OHV straight six. So
far so good, well over 200 miles and 20 years!!
I think the 68 - 87 Jaguar saloons and the XJS share a
platform. In theory, the pipes that fit the S’s series
saloons and the XJS can be exchanged.
I got a pair of new iron ram horns with my engine trans
package. From the boxes, I could not tell the ID of the
maker. Definitely no sign of the generator bracket of
originals. sand straight across rather than having two
lumps giving them the ram horn name.
They included four ports each for an air rail. I revised an
ancient pair for SMOG folk’s pleasure. I chose not to try
to drill and tap for the LT! fittings. Big holes concerned
me.
I did have to grind a considerable bit of metal away to get
valve cover clearance. Plenty of meat and it came off well.
Plus, a small flat to drill and tap for the EGR take off. I
used the GM pipe, it looked like it was done by the factory
when done.
Alas, I chose not to port match. Pushing my luck on the
mod’s already!!!
And, High temp O2 safe RTV in lieu of gaskets. worked just
fine. Except a flange gasket of some composition, they came
with the horns, I think!!
Oh, my 94 LT1 is iron headed, kinda like some say I am.
Bending the down pipes, duck soup for you. Mine came from
Andrew’s affiliate in Florida, Sun Coast. I drilled and
welded on a bung for the O2 sensors. Came out just fine.
The driver side pipe had a slight jog built in to clear the
steering.
Alas, I’ll probably have to drop a down pige out the
starter… Dreaming of 70F to do that job in.
Not enough demand to develop headers of your design, I
suppose.
