440 - Best Intake & Carb???

Post by McMOPAR on Mon Nov 14, 2016 6:56 am

Hi guys,

Instead of rebuilding the tired 383 in my 70 Challenger RT, I bought a recently rebuilt 440. It's bored .030" over, has a Mopar 557 cam, 906 Heads, Mopar M1 aluminum single plane intake manifold, Holley DP carb, long tube headers, is claimed to have 500hp/525tq. Previous owner claimed it ran 12.8 in the 1/4 mile in his 69 Coronet. He has decided to keep the intake and carb, so I would like to know what will work best on this engine. It will be used 90% of the time as a cruiser to car shows and local cruise nights and then 10% of the time at the drag track posing as a 383 car. Based on my research so far, I'm leaning toward a Mopar dual plane aluminum intake or the Edelbrock Performer RPM for less hp and more tq. For the carb I'm wondering if I should just run the Edelbrock AVS 650cfm (1806) that was on my 383, or get a Edelbrock Performer 750cfm carb for it? I'm just not sure if the 650 is too small for the 440 seeing as its not stock. One other thing I will have to figure out is which stall speed torque converter to run with this engine...

You can't go wrong with an Holley 3310, 750 cfm vaccumm secondary

I do like the holley carbs for easy jetting and setting up but also like the out of the box performance of the Edelbrock Performer carbs. The thing I find is it's not as easy to change the jetting on the Edelbrock Carbs, But I will second go with a 750cfm for size.

For converter I would go with a 3000 stall, I believe that cam has 252 @ 50. That cam in a 440 probably starts working close to 3000rpm.

Both the intakes you listed should work ok, but like you said you will loose top end hp. Edelbrock 7193, or even a torker II single plane, I think the range for the torker is around 2200 - 2500 rpm starting rpm.

I'm running a Holley street dominator intake and a 850 Quickfuel carb. This one. (Works great no hood clearance issues. VERY adjustable carb!)

Good to see you over here too! Very Happy

I have an Edy RPM air gap performer intake and Edy 650 carb and have not had an issue pretty much ran right out of the box. I am running a 360.

I talked to my engine builder last night and we have a plan. We are going to replace the Mopar 557 cam (3000-6700rpm), with a Hughes Whiplash cam (1500-6500rpm). Install an Eddy Performance RPM intake, and use my Eddy AVS 650 carb. We will also install a 3000 stall converter in the 727 trans. Does anyone here have experience with the Whiplash cam? I have only read good reviews so far, and it seems like it’s exactly what I’m looking for. From the videos I’ve watched, it actually sounds meaner then the Mopar 557 cam at idle but then starts making power 1500rpm sooner than the 557. You could almost say the best of both worlds.

The whiplash cam is a way better choice than the old mopar grind and your choice of intake will work great with that cam .the 650avs carb would not be my choice and as for a converter call a good converter company like ultimate Dynamic or Turbo action and get one made to suite your combo an off the shelf converter is hit or miss don't cheap out on this important part . jmo good luck .

Yea I agree! With that cam change it will work well with that rpm performer intake. I'm thinking a tad lower for stall speed, I think I would go with a 2500 for the 440. With a smallish carb that intake and a drop in cam you'll be making a ton of torque before 2500.
