Are you saying mine is a Thermoquad? I rebuilt mine
but am having running problems and am considering the rebuild service at
Carburetors and more in Phoenix Arizona for 115.00. They say they rebuild and
test your carb on a live engine. Has anyone dealt with them?
Thx,

The carb size question is misleading because it depends on the relative
size of the primaries vs. the secondaries.
The Thermoquad carbs had very large secondaries relative to the
primaries. I believe that they were typically rated at 895 CFM, but most
of that was through the secondaries which are not used in "normal"
driving.

I have an Edelbrock AVS-clone
with electric
choke on my '69. Works great, even though the
jets
aren't quite right.
All it 'needs' is a 650, which is about what
the
factory unit was. If you want more high-rpm
hp, then you might want a
bigger carb. If it
has the HP cam or something like it, a 780 is
what's reccommended around these parts.
My understanding is that (for
some reason I
don't get) the bigger carbs boost your high-end
horsepower, but hurt your low-end torque (at
least unless you change
other stuff too), so
you might not want bigger.
