there is one on racing junk in great condition for 300, what are you going to do with the car? cruiser, street/strip?

I like the idea of a six pac setup as well, the cost and initial setup is huge. I have seen several 440 6 pac motors here on the dyno, and the engine builder has fits lol doing jet changes to get it right. It seems legit, that you would be running a 383 2 bbl etc until you wack the throttle wide open then you have a **** ton of cfm.
Any idea of what the total cfm of carbs are once the outboards are all in? i know my 426 build only used 638 cfm. I know the small block carbs are less cfm than the big block ones, or so i have been told.

Fisher I agree, the thought of running on a two barrel and then having four more available just sound cool. I would assume mileage would be better than with a single four IF I was able to tune/adjust them correctly. Cost, like you said, is way above a single four setup with e carbs, linkage, air cleaner assembly, etc. I've also heard numerous times a single four setup will outrun the six pack everything else being equal? I guess the cool thing is just the visual effect and to be able to say you have one. Question though, if a single four is better at the track, why were the six pack cars able to keep up with the hemisphere, but beat the 440 4 barrels.

The factory stock 440 + 6 motors i have seen on the dyno here, even with manifolds. were only able to make 404 hp and 450-460 TQ. thats pretty much what they were rated at. Headers cam and some tuning would wake them up.
