Carb question for a 440 - 01/29/11 04:41 PM
Would a holley 350 two barrel carb be enough for a 74 440? It will be for off road use if it makes a difference and it is a stock motor. Thanks in advance.

If you want a VERY narrow powerband.
It would have awesome throttle response, but peak low.

How about a Holley 600 4bbl?

No, the factory didn't even put a two barrel on a 440, even with the tiny cam that came in the regular low performance engine. The smallest I would is a 600 cfm 4 barrel.
It will work, but you're really choking that engine.

I suppose in the right application (pickup truck just doing light chores never over 4000-4500????) it would be fine.
Any sort of WOT work (full-throttle)? Not so ideal.

Absolutely. But you've to to add two 500 two barrel carbs on either side of it.

Nope. You could try a FoMoCo 500 or 600 2 bbl. a better question would be why?

I guess b/c I have one sitting around. Anybody have a 500 or 600 2 barrel they want to sell? I'm not wanting a 4 barrel for this one for gas reasons.

4 Barrel carbs get a bad rap for mpgs. A small 4 barrel can actually deliver really GOOD mpg if the driver keeps his foot out of it!
Think about it, if the secondaries are not used, what do you have? A small 2 barrel! (in effect)
Oh, AND, BIG 2 barrels (like 500-600cfm) usually provide poor throttle response AND poor mpg. Don;t go that route!!!

I have a Motorcraft 4100 4brl off my 1965 Galaxie that would work perfect. I think it was 450cfm??

You can always use a 383-400 2 bbl intake man with some stage VI spacers, if you're going with the 2 bbl.

you have what sitting around? as mentioned before no 440 EVER came w/ a 2bbl so you'd have to use an adaptor. A stockish 440 w/ a small 4bbl should get 15+mph.

Are you sure it's for an RB block?
If it is, it's a very scarce 413 truck intake.

Re: Carb question for a 440 - 01/29/11 10:16 PM
I have the carb laying around. No 2 barrel intake. So yes I would need an adapter if I go with the 2 barrel.

Will not fit.361,383,400 are low deck blocks.440 is an RB deck block.

Re: Carb question for a 440 - 01/29/11 11:09 PM
That's what the stage VI spacers do. Make low deck intakes fit RB.

The "small" cfm 4 bbls work better, especially if you have the standard 440 (non-Magnum or C-body 440) cam. Either 600 Holley 4160, 625 Eddy AFB/ 650 AVS OR the 340 750-800 cfm TQ. The TQ, when set up correctly, will get good gas mileage for its
cfm rating. Never count it out!! Any one of these carbs would be okay for what you desire to do with the motor. Trial and error jetting and ignition adjustments will get you to your goal.

THIS is why the ThermoQuad is such a good piece. But do NOT let a died-in-the-wool Berri-Bumz try and tweak it.

Sell the 440 ( to me, for cheap preferably)and buy a 318. Better gas mileage and tailor made for a 2v.

Or you can find a RB 383 intake from 1959 and bolt a two barrel on a 440.
