Hello everyone my first time here. Can anyone tell me how much horse power u need to run 2 500 carbs on a 440

 

375HP....

Just my 2 cents

Welcome to the site....

 

Need 1000 cfm, or want a cool two carb setup for your 440, that is the question..........
..hmmmm

 

Chryslers "Six Pack" of 1200 cfm advertised at 390 HP. Center carb only and outside carbs on demand based on engine vacuum, load.

Two 4 barrels would depend on progressive or vacuum opening with camshaft "size" to make an efficient system. Manifold height will also be a factor to consider.

 

You have a very open question there , what carbs and manafold are you thinking about?

 

 

 

The cam is a284-484 and I'm thinking bout a Edlebrock 5440 intake and Edlebrock 500 carbs

 

How much compression do you have?

 

I think it was on engine masters on the Hot Rod utube chanel they did that setup on a sbc, you might have a look. If I remember it made good power but has been awhile.

 

What is your combo ?? 284/484 Ah a purple shaft cam.. It needs a 2800 stall converter and should have a min 3.55 gear

 

Compression is 11.5 to 1 I'm using 3500 stahl with 3:55 gear

 

Compression is 11.5 to 1 I'm using 3500 stahl with 3:55 gear im going to change to 3:90

 

What are you using for heads?

 

Heads r 452s but im going to go to 906s

The 452s make slightly more power than the 906s with cam lifts below .560 lift. With the compression ratio and the converter you have a larger cam like the .557 mechanical or the .509 if you wanted to stay with hydraulic. Ive got a 9.5 motor that makes 520 whith the .557 cam and 452 heads. Heads have been pocket ported and 2.14/1.81s fitted. Very straight forward build.

Just curious about what you're looking at for fuel?

 

I've been running 91 octane cause it's hard to find anything better where I live but my truck runs pretty good right now on 91 but right now I'm running a 750 edelbrock
