I bought a 1972 charger with a 318. I bought a 440 out of a 1973 Winnebago. I currently have the block in a machine shop getting it reworked. I was told its a good block. with a steel crank and six pack rods. I need help finding the right cam shaft to replace the old one. I want it to sound good but don't want anything to radical. I am going back with stock pistons and heads. Any help would be appreciated. also I bought a aluminum intake looking for a decent 4bbl carb any recommendations. Thanks in advance.

 

Without knowing the heads and the cars intended use picking a cam is like putting the cart before the horse? More info needed?

 

aluminum intake and "decent 4 barrel carb" already lost my interest in helping you.

 

Sorry I am new to this. I don't know the right wordage. I am doing this rebuild on a budget. I don't have 10k to invest in my motor. I wish i did. I was planning on using the factory 727 tranny and it will be a weekend driver car. Sorry I am new. I thought this was a place where I could get help. I work for a living. I am a cable guy. I don't have a lot of money. I have about 1500.00 total to invest in my motor. that was my tax return this year. I am removing the cam because it was in a Winnebago, basically a truck motor. I want a nice sound and i was told that lope sound comes from the cam. I don't want a to radical cam because I was hoping to use the factory torque converter. I am cool with any feed back anyone has to offer. the shop where I have the motor in says he needs a cam and lifters before he can finish his part. also brass freeze plugs. I am still learning so please excuse my new ness.

 

I don't know if you're motor is a single bolt gear cam? Comp cam 268 http://www.jegs.com/i/Comp-Cams/249/...rentProductId= is about the biggest cam for a stock torque converter and gearing. They do make the comp 268 in a 3 bolt gear also. Also you will need to upgrade the valve springs on you're heads.

 

Being on a budget you're best bet is to ebay that intake you have. Pickup a set of 516 closed chamber heads "they are dirt cheap nobody wants them".

Only install the 1.74 exaust valves and have harden seats installed. Get a .020 thick steel shim heads gasket set. This intake http://www.jegs.com/p/Weiand/Weiand-...46531/10002/-1 is by far the best intake to use for 516 heads. I have tried them all and that one works the best for the heads. No port matching will be needed.
Carb the 4150 holly 750 with mechanical secondaries and a jet kit "learn how to tune and change jets" which is very easy to do with hollys IMO. COMP 268 cam that intake and heads with the 750 you will be very happy for a very hard pulling torque monster for the $.

 

No need to apologize here. I value the dollar big time and everyone starts somewhere.

I needed the head info so you didn't to waste any money with an "off the hip" recommendation.

First thing you need to do is call the machine shop and ask the following:

What heads are on there and what replacement piston is going to be used so you can get your compression ratio?

With 1500 dollar budget you should build this in steps. At least 1/2 of that money will be used on the short block if he is assembling and possible 2/3 depending on the head work.

Assuming you have 500 (hopefully) left I would get a replacement cam in there that lets you add headers and an intake on there later.

The machine shop can install your cam and springs on the heads. If you are a communications tech you can cut your teeth on intake and headers later and will have zero issues.

Comp cams XE268H with the 911 spring will run nicely. Its a very snappy cam and with a header will "bump" slightly at idle. she will not "slap" at idle at all. So this really doesnt get you the huge sound but gets you a great runner for your application. She will be quieter with exhaust manifolds but just fine so you can step the build in stages. It will also run with stock converter in the 727.

 

Bobby -

You have nothing to apologize for.

Work with your machine shop.
Don't do anything that isn't necessary.
For example, don't overbore the cylinders if all they need is a good polishing. That way you can use the old pistons. Sure, you'll get less compression and more weight than with new pistons, but as a weekend fun car and not a 1/4 screamer, it really isn't going to matter (depends on the end game for the car.)

Spend your money on a good balancing job and REQUIRED head work. The heads you have may not be the highest performing heads, but are serviceable. Otherwise look for 69-71 heads and rework accordingly. (Valves job, springs, etc if original).

There are a lot of cams that will make a good weekend car, and anything near or a little above stock will be fine, and you won't have vacuum issues to worry about. Yes, you'll need a new timing chain set, lifters and pushrods.

You are correct, almost any decent dual plane aluminum macifold and appropriately sized Edelbrock or Holley carb, 650 - 750 CFM will be fine.

You already have an electionic ignition and the mopar dist/ECU is fine. If you're edgy, a mopar replacement set isn't expensive.

You will need a big block tranny (the 318 tranny won't bolt up) and a mount conversion kit from Schumacker (to get the 440 into the 318 frame).

That's just a 30,000' view and welcome aboard.

You do know that the aftermarket dual plane intake manifolds are the 69-71 cast iron ones recast right? The carb plate area is different along with the choke (which doesnt work on the aluminum anyways so you have to go with the electric) at least all the ones I have seen from weiland or elderbrock are. The unmarked aluminum mopar perforance seem to be the 70 style choke well but the same thing.

The Edlebrock manifolds are avaiable in a square bore and and spread bore design. While a choke may be nice, in all honestly with the right size carb, it isn't even necessary. I can start my old school 440 in the dead of winter with a little careful peddle action and the choke plate has been removed

Aluminum is lighter and dissipates heat more efficiently.

You know this stuff.

Here are some Youtube sound clips of 440s with cams.
More than not, in the comments for the respective video, you can find out what the cam specs are in the car. If not.... it's still fun! lol

I tried to add the Youtube page and it didn't work. Try 440 Mopar Cam in the Youtube search field.
