1 four barrel vs 2 four barrels

[Jac Mac]

Anytime this subject comes up my answer goes along these lines... If Nascar can get close on 900 hp and 200mph in a sedan body out of 358 cu in and one 4 barrel what is the point of any more, as you can probably guess I am not into show and shine!

I had 2 4s on my 64 Galaxie 427 and I have had much better luck and performance with a well tuned single 4. When going around a turn hard the Galaxie would tend to splash fuel away from the jets and it would stumble, not a good thing in a hard turn. All of my cars since then have had single 4s or fuel injection. The 2 4s look good at car shows but I don't do them.

OK Ron - if you managed to starve a 2x4 427 in a "hard" turn with a "64 Galaxie" that definitely establishes that side hung floats are sensitive to cornering.

Dan,

I did it a couple of times but I had good suspension and that car wasn't made for road racing anyway. When I got my first Cobra and set it up for the road track I just used a single 4 and it worked m great and I never noticed any loss of power either.

Yes, agree.

I would rather spend a little more on a HIGH quality single four barrel and intake manifold, than fit "old school" Holleys.

There are some many choices: Pro Systems, TMP carbs, C & S Aerosol carbs, QFT, etc etc.

My favourite would be from TMP, 1000cfm annular, Weber emulsion blocks, WOT from 1500 rpm, pulls better than EFI.

I totally agree. Work with one of the guys like Pro Systems, give them your engine specs, and trust them to build what you really need. Not pushing Pro Systems, but any of the good guys will bench flow and test before they send it.
In my case it came out to an 858 cfm with manual secondaries and it rocks.
