2x4 or 3x2 for best drivability on a mild engine?

Thanks for the input everyone.

I've browsed around on Jay's forum, not sure if I registered there or not ... good plan though, he certainly knows his FE inductions!

Then you'll know he has published a book, the Great FE Intake Comparo or some such title, which gets rave reviews.

Haven't bought it myself but I do have Barry R's FE book "How to Build Max-Performance Ford FE Engines" published by CarTech books-- well worth the $$$. Chapter 10 is all about intake manifold set-ups.

I'm pretty sure that Jay's book will tell me that the intakes I'm considering are crap for making power ... LOL

this vid is still in my favorites:

if its an old draft cam, they will be tight at the intake valve timing side (3 to single digit degrees before they start to open btdc) do anything you want. it won't be difficult to get going.

they don't just slobber a difficulty..they tease for more air, not really a nascar result.
the fat lobes is where rocket science is needed on big old school draft.

TC, keep in mind that this is a 4,200 lb. car with an auto box and 3.00 gears ... it would be hard pressed to see the high side of 4000 rpm. So 500 cfm should do the trick I believe. Edelbrock has some of their 500 AVS carbs that are specifically calibrated for a 2x4 on a mild larger displacement engine.

Bob, the 3x2 system that I am looking at does have the outer carbs as you describe. The primary is a manual choke, I would have to look at what it might take to convert it to electric ... a hand choke just doesn't seem right on a classy car like a Thunderbird that has power everything else.

get the right choke knob that matches the radio knobs...

I don't know if I get the "tuning three carbs" thing sometimes. Every sport bike I owned had 4, and they were all on all the time. The 3x2 gives an interesting deal with progressive tuning. If they never get pulled on, it's not all that big a deal. Tuning for WFO is like reading plugs? They don't have to be "Synched" like a non-progressive setup does. I may be talking out of my butt here, but I don't drive with my foot in 6 barrels all the time either. I'd probably on be on 2 most of the time.

that said, and having stated that I'm an idiot - this is just too cool looking.



I'd probably go that way over the 2x4.

3x2 Coolness

Further to Beagle's post above, this is looking good too. Seen at Henderson NC today in a very sweet 64 Galaxie from VA.

Is that a custom inner fender well or is that MSD box just mounted where a cruise control unit or something would be?

Or something....the windshield washer bag

I missed this one... 3x2 fer sure. Variable intake runner length, high velocity central plenums, high flow outer bodies...It works. Dove FE wedge with a 3x2 top...Super EZ to tune and keep tuned too! Fitting a FAST dual sync distributor is a problem though. Dont need no Chevy cap on my Ford set-up at any rate. This one goes on a 427 in a 67 fastback Mustang.

That is very sweet ... something like that would be an ultimate setup for me. Unfortunately I'm sure that it costs as much as or more than I paid for the whole car! LOL
