Hello,

I am considering updating the carburetor setup on my MkI BT7 to match the
configuration used on the factory rally cars. I have seen photos of the
Rudd Speed triple HD6 arrangement and was wondering if this is the setup
the rally cars utilized.

Any information or photos you could provide would be greatly appreciated.
My goal is to ensure the setup remains period-correct.

Thanks,
Harold

<div>Harold-I had an opportunity to take a couple of photos of both setups =
from early days at a friends garage. Initially the three H6 or HS6 (1-1/2")=
 carbs were used as they were factory. Later they changed to Weber 45s. =
Here are photos of both. The Weber setup is a bit much for the Healey 6 =
engine and it takes some patience to jet it to get a smooth running car. It=
 must have a balance pipe to control midrange.</div>
<div>&nbsp;</div>
<div>The best setup, recommended by my friend, is using the three HD6 =
(1-3/4") carbs for serious road use or track-as shown in the photo.&nbsp; =
BMC should have gone with the larger throat and it would have lasted longer=
 than just one year in the tri configuration. Three HD8s are too much for =
the setup as well<br><br></div>
<div>If interested-some of this stuff might=
 be for sale. Happy New Year. Hank-------------------&nbsp;<br><br>From: =

<div>Thanks David. I am =
interested in the triple&nbsp;SU engines. Does Robson book say if the carbs=
 HD6 or HD8? Does anyone&nbsp;have a picture of the 1960 triple SU engine?
