Hi,

I was quoting list prices for the carbs from TRF and Moss. If you go to 
the other Weber places, you'll likely pay less for the carbs, but be 
careful what you are buying - getting all the little do-dahs for a triple 
Weber setup is no cheap. Example - getting the wrong manifold (early/late 
TR6, for example). That mistake set me back around $350 bucks. Of course 
now I have two early manifolds and one late style... I'll have to put 
another set of Webers on one of my cars!

FWIW, the used Weber DCOE40 set that I bought, the guy paid the $1800 or
so and then paid some clowns a lot of money to "tune them". They ran like
$#!^ when I got them, owing to the idle mixture screws having been turned
out _8 turns_ to get the car to idle. Can you spell "wrong idle jets"??? I
knew you could. 

As for buying used Webers, because DCOE40's have been around so long, 
there are lots of "revisions" available. I would be concerned about 
making certain revisions work together - so make sure that all three are 
the same thing, DCOE40 model 151, for example. I agree that they show up 
for $600 from time to time, that's how I bought mine, but make sure you 
know what you are getting.

With regard to the triple stromberg/su setups... I've read that Vizard 
book too. I agree that more air will flow than a set of twin strombergs 
or SU's would... one funny data point is that a respected tuner told me 
recently that he wasn't sure the setup was any better than the DCOE 40's 
or a teaked set of SU's. I def. respect this person's opinion, so I'll 
take a wait and see attitude towards the triple SU's. I do know that R 
Good claims numbers like you quoted from the Vizard book, so it could 
very well be true.

There is another option, that I forgot to mention... some folks use twin 
HS8 SU's - you need to modify the manifold or make an adapter, but these 
will flow a lot more than the HS6's...

Ah, decisions, decisions.
