[v12-engine] Header Plate

V12-Engine
1

I am looking for a header plate so we can build up an exhaust
system for the XJ13 replica. I have someone who can do the job if I
can find the template. I am willing to buy, borrow, barter etc.

My engine is a 6 liter but I am pretty sure that 5.3 and 6.0 have
the same template.–

give the welder an exhaust manifold, and have him trace one
from the flange pattern. ?–

Mike,

I have a CAD drawing of the Gp C exhaust ports with stud locations. I don’t
know if the port outlets exactly matched the standard head. Certainly the
shape is different. I do have a standard flat head I could take some
measurements of if you need …

I recall puzzling (as I reverse engineered this engine) trying to find
whether people who machined it were using metric or imperial measurements.
My conclusion was it was a mish mash of things. (Like 10ths of an inch,
standard metric and then good old imperial) The bore spacing is a case in
point. Some bizarre number.

Thanks Ron I do have a set of stock manifolds I can send to the
fabricator and we should be able to build up from there.–
