I=E2=80=99m probably bucking the trends here. I run the stainless falcon tri=

avor low to mid range torque over high rpm horsepower. Since I built my race=
 motor around the concept of accentuating torque, I went with these. Been ru=
nning them since 2010 and they are still in great condition. Do I make the m=

One draw back with my engine combo. It drops out of that nice fat torque cur=
ve at anything over 6500. I know some other guys that run TR 3/4 motors that=

I guess it comes down to the whole package. Match your headers to your engin=

These are the headers I ran on my TR3A, TR4, and Warwick GT.
They came from Cambridge Motor Sports in the UK when they were
in business. I think they were the same as what Ken sold at BFE.
        One of these sets went to Henry Frye. Watch out, they might be
on Ole Blue at the Kcup.

Need a Set? Buy my TR4, get the header.

Thanks Dean, the Cambridge headers are installed on Old Blue! 

The Cambridge headers are not the same as Ken Gillanders supplied to so
many of us over the years, but I have no doubt the same manufacturer was
responsible for making both. The primaries on Ken's header were
significantly shorter, the collector was on the straight section of pipe
under the starter. I have not had Old Blue on track yet with the
Cambridge header, but I made so many other changes this rebuild that I
am afraid I will not really be able to say what kind of difference they
make. 

Gillanders believed headers with the 1 5/8's inch primaries were the way
to go, he had all the fast TR3/4 racers in the east running them. The
vast majority of TR3/4 headers we see, and as Bob Kramer states, we all
have hanging on our walls, have smaller primary tubes, usually 1 1/2
inch. 

It seems every year or so a racer is looking for a header for a TR3/4,
and as there doesn't appear to be an obvious supplier, it turns into a
scramble. 

Do we know if somebody selling TR3/4 headers with the larger primary
tubes? 

We know a lot of work has been done comparing the length of the primary
tubes, but has anyone done any dyno work comparing headers with
different primary tube diameters???

Where are the Engine Masters when we need them? Some dyno time would be
terrific.

If my memory is working today, Cambridge sold these in two different
lengths. I bought
the long ones. Ken might have sold the shorter ones. It would not be hard
to shorten those
and move the collector up. Would make them easier to fit on a TR3A. I still
have a set on the
TR4. The ones you have were on the Warwick GT with 42 DCOE carbs.

Happy Thanksgiving everyone

<p>Thanks Dean, the Cambridge headers are installed on Old Blue!</p>
<p>The Cambridge headers are not the same as Ken Gillanders supplied to so =
many of us over the years, but I have no doubt the same manufacturer was re=
sponsible for making both. The primaries on Ken&#39;s header were significa=
ntly shorter, the collector was on the straight section of pipe under the s=
tarter. I have not had Old Blue on track yet with the Cambridge header, but=
 I made so many other changes this rebuild that I am afraid I will not real=

<p>Gillanders believed headers with the 1 5/8&#39;s inch primaries were the=
 way to go, he had all the fast TR3/4 racers in the east running them. The =
