440 intake

[Stacked440]

I have a TM7 that came on my 440 when I bought the car 2 years ago...however I just received information that the TM7 is really only effective on the strip, not really designed for street/cruiser.  There was another thread that suggested a Holley Street Dominator intake.  Would that work well for my motor? It has a 670cfm holley street avenger on it and a stock cam.  Lemme know, now is the time I can change with relative ease!

you really cant go wrong with the eddy performer RPM. The street dominator is very similar. Either one would work

[Stacked440]

The only one summit lists for a 440 holley street dominator has an EGR, I don't want an EGR.  do they make them without them that I'm just not seeing?  Or is there someway that having the EGR doesn't matter or what?

all Street Dom intakes have EGR provision , I have never used the EGR ports , they are easily blocked with no bad effect ,, the Street dom is a great intake part # 300-14 for 440
 my questionis the 670 CM carb , far too small for a 440 unless you are under 4000 rpm all the time

Didn't 440's come from the factory with 650 carters on them?

[Chryco Psycho]

Probably but the 440 also came with 3- 2bbls & close to 1000 CFM & they run better that way

What do I have to do to block off the EGR on the street dominator?

thread in the pipe plugs included with the intake

Probably but the 440 also came with 3- 2bbls & close to 1000 CFM & they run better that way 

Center carb is 350 cfm and the outboards are 500 cfm's each...= 1350 cfm

Thats why we get the trademark ' bog ' when we open those outboards...

But THEN...

[Chryco Psycho]

well that is sort of correct Except that 2 bbls carbs are flow rated at 3" of vacuum & 4 bbls are rated at 1.5" of vacuum so the actual flow cannot be directly compared & if they are tuned correctly there is no bog just tire smoke 

[MG440RT]

I stand corrected...sort of .

I just completly rebuilt my 6 pack carbs, and so far I have no bogs at all and the throttle response is right there when I need it I built them back stock specs and must of did them right.

I am either lucky, or I have built a few holleys and 6pks before

But seriously, when set up right, they work like they were intended to. Take no short cuts and know how to tune an engine, not just carbs
