Helping out a friend with a 440 build. He was looking to pick up a good used intake and asked what I thought he should be looking for. So, I am open to a good selection of intakes that would work good for this combination.

440 .030 over using a KB237 set at 0 deck height. FelPro 8519PT head gaskets and 66 small valve closed chamber heads. Heads have been bowl ported and cleaned up. Compression at 11:1 and is using a 509 Mopar performance cam. He is putting this in a 66 Belvedere that has a 3000 stall converter and 3:91 gears.

Thanks
Dan.

I am HARDLY a Berry-Bumz .. in fact .. I am the Prez of the ThermoSquad ...

But you can't go wrong with the Holley SD !

Holley street dominator or edelbrock rpm.

Performer RPM or Torker II would be good.The RPM will be about $100 more than the Torker II
He has enough gear and converter to use the single plane
Gus

it really isnt going to matter much as to what he gets.
he first needs to fix his miss matched componente.

with that 509 cam being a high RPM cam and the small port/valves heads not being high flow heads he has a major problem.

So IMO with a much better cam and set of 906/346/452 heads a Street Dominator or a Performer RPM and he is going to have a killer engine..

edlebrock rpm heads

edelbrock rpm intake

Do you plan on running headers or manifolds?

He is using headers.

With a target of 11:1 CR and iron heads I assume this is a race gas engine? The "rule of thumb" is pump gas is limited to 9.5:1 with iron heads.

The "0" deck pistons are a great building block. The '66 heads (915 I assume) would provide quench and make a great pump gas street head at 9.5:1 or a bit more. With the 915 head this would require a "D" dish piston to lower compression and still provide quench. Agree the Ed heads would be a better choice. Un milled, compression would be around 10.5:1 which should be OK with pump premium with aluminum heads and quench. If higher race gas compression is desired, the heads can be milled down. The big plus either way is better breathing compared to the 915's. The iron heads can be upgraded with bigger valves but its easy to put more $ into them than a new set of aluminum heads.

66 heads will be 516's not 915's.

11:1 is a nice match for that cam, and stall speed.

I agree that the small valve 516's are less than ideal, but it'll run. I wouldn't be afraid to try it before I poured my money into aluminum heads.

It'll be iffy on pump gas for sure but a smaller cam won't help. The compression has to be reduced if that ia a concern. I suppose that would ba a plus to the eddy's too, in that the alum head will work with pump gas at 11:1 and that cam.

Is this a street car or stip only car ? Ron

The car is used for weekend cruising and he is mixing fuels. I didn't want to see more than 10.5 compression, but he seems to think he wants 11. Will he be fighting detonation at 11.1? I have not cut the heads yet, so the compression number can be changed.
It's been awhile since I looked at the heads, but I know they are a closed chamber small valve and I thought they were 915's.
Did the 67 440 HP engines with the 915's flow better, or was it the same casting/ports with a larger valve only.
Would this combo he has work better with,say a 906 and a little less compression and still use the 509 cam? I think he will be happier with a engine that makes a ton of bottom to mid range torque for what he wants to do. Top end is not his thing, smoky burn outs are



Thanks
Dan

RPM performer hands down (Holley SD good too)
509 cam degree it in to 102 or 103 intake installed centerline (max lift)

My big big vote is to bite the bullet and get RPM heads no fuel issues with a 509 cam will be able to run 91 octane.

If you must but long before you spent on a crapy old poor poor flowing heads go with 440 source. I just finished hand porting a set and they "ARE NOT EDELBROCKS" no way they will flow perform or match an eddy!!!!! (maybe close after hand porting) But they will out flow even a hand ported iron heads and still allow 91 octane and I'll bet they will produce 75to 100 more hp than those 66 516 heads

Please don't use those 45 year old crack prone million heat cycle iron heads unless they have new valves and guides (you don't want a million heat cycle valve breaking off and hammering the motor apart) new valve springs, retainers and keepers. AND they must be free with all this done or you are throwing the money in the toilet.
So if someone gives you a set of done fresh all new 516 use them But if you have to pay anything for them run!!!!

Holley Sd is about the best all around intake made.Has the manners of a dual plane runs like a sinlge.Rocky

If he's set on keeping the 516 iron heads, 11:1 and 509, run it on E85.
If E85 is out and he wants to run 93 octane, a change to cleaned up 452s is needed. He should make more power with 452s at 10.25:1 than 516s at 11:1 because he will have to take so much timing out to stop detonation. The better 452 ports is an added plus.
Intake? The Holley Street Dom would be my first choice.

Thanks guys. My mistake on the head casting numbers, they are the 516's. He had these heads gone through a couple of years ago, and used them on a 383. They don't have a lot of run time. It's his engine and $$, so I can only make suggestions.
What can a 452 or 906 casting be milled to as far as CC's and still be safe? Could he get 10:5 compression or more with one of these castings using the pistons he has?

Dan

I run the Holley Street Dominator on my 440 in my 63 and it works real good for me. And we have the RPM on the 400 in my boys Dart which runs real good also. For a street/strip car with standard ports you cant go wrong with the Holley SD or the RPM intake. Ron

I have a feeling your friend wants 11:1 compression so he can say he has eleven to one compression. Sounds more badazz than saying you have ten and a half to one. I bet the difference between 10.5 and 11.0 wouldn't be more than 5 hp on that engine. Not enough to justify mixing fuels, IMO.

It's not worth spending 7 dollars a gallon on fuel just to do burn outs. Forget the 11 to 1 compression for a street motor. You don't need 11to1 to pull a good smoky burnout. I think this is more about bragging rights then performence.

I can tell you my 906 iron headed 440 in my 63 came out to 10.0 comp after I used the right head gasket with the 906 heads. I run 38 total timing all in by 2000 rpm and I use the MP .557 cam. It runs great on 92 pump with no ping at all. I do use the quench pad pistons from KB as I got the quench on all cylinders in the .040 to .045 area. But it is nice to drive to the track and stop along the way to get pump gas in the 2 to 3 dollar range and not have to get race gas at the track for 8 bucks or so ! I figured if I ran 11.5 or 12.0 comp it would only be worth a tenth or two and its not worth it to me as I will give up a tenth or two to save money as I never have enough money now as it is. Ron

So the intake manifolds suggested are good. In addition, Id use 383mans cam MP 557 solid. If only hyd cam is possible, get on the phone with Comp or others here to match a good cam for you. That 509 is a big cam for those small heads. It requires a high stall and gears to really work. There are others out there that will be a better match to your combo as posted.
