Kinda depends, lot easier to put the t-quad on a good manifold. The 6 pack problem is the manifolds not the carb, unless you are me and can't get a holley to run right for nothin. T-quads run great and are easy to work on.

gets to be a pain to jet a t-quad when there are no aftermarket jets and rods. i have to scrounge for jets and drill them out on the lathe to get A/F ratio close.

They only flow 1300 if you flow them a 3.0 inches like 2bbls aree flowed. If you flow a 6pk at 1.5 like the 4bbls are then it will strugle to flow 1000 cfm, or about the same as a good T-quad and you are still stuck with a 6pk manifold, a simple adapter can fit a t-quad to just about any manifold.

HotRodDave has it right. According to the resident Mopar junky over at Hot Rod Magazine (David Freiburger,) in terms of 4-barrel air flow the mighty Six-Pack flowed closer to 975cfm because 2-barrel carbs are rated using different specs.

Throw on a street tuned Holley 950HP on an Edelbrock Performer RPM intake and there you go...

As someone who has run both I'll take a TQ anyday.

I have two TQ strip kits on the shelf!

Better selection for single 4 manifolds than six pack for starters. A properly setup thermoquad will deliver better fuel economy and more horsepower. Dave

My take ? .... I think I should make a TON of T-shirts proclaiming .....The ThermoSquad is alive and well !!

And from what I have seen and read ...Mayor Dave has done a ton-O-work of the TQ when it comes to a E85 conversion ...

I have not done much lately on TQ R&D and tweaking as he has .... we should get HIS TAKE ...and maybe Scott's.

Good point to about, Dave! I was wondering why when you increase the cubes, especially 440 strokers, you get an abundance of
low to midrange torque and decent mileage (provided the cam, compression and ignition timing
are correct for the combo)in a middle weight chassis (B-body stripper model) with the six pack induction.

Good food for !! That E85 fuel may be the
answer to the cost of cruising. Good input Doc,
I figured you to come up with a answer WITHOUT the
added sarcasm!!

Dave, comparing a six pack to a TQ setup, on a
stroker (440/500) built for dual purpose, which
would net a tractable, but powerful setup? Six
packs have been known to do well with bigger displacements, but I know there's a limit.
TQ's are very responsive, but have their parameters also. What do you think?

But being so close in airflow, would the six pack
have more flow capability upstairs? Due to the two extra venturis? Or not.
