I'm going to be the a-hole here and say this. Since you are getting advice from the guy you trust at work, why even ask here about what you need? The majority has said that cam is to big, yet you don't listen. If what you are looking for is intake and carb, go ask the guy who sold you that cam and said it will work. That way you will get information from someone you trust...... I will keep tabs on this to see how it turns out. Good luck!

You will need a clutch or high rpm stall converter. This engine will be a mutt off idle "outta the hole" and then feel like someone flicked a switch on at 3500 rpm and go like hell.
How about grab a period once in awhile.

Really , spending all that money and sticking with a 60.00 cam ?? Stick with your big mopar guy , he must know something nobody here knows . Just don't expect to win any light to light blasts , unless it's 1/2 mile between lights .

That 509 cam didnt wake up for me, in my Eddy headed, 11.2cr, .020quench,360, til after 4500 but pulled to to 7200 real nice.My 232@050 cam, at 10.7cr, is waaaay more fun.And it still pulls to 7000plus. Or did I mention that already?
The 509 cam had only one thing about it I liked; the lumpy idle.My fast-rate 232 sounds tame in comparison.
To bring that into perspective(its being a mutt till 4500),consider this; If you have a 904 and 3.55s then, 4500rpm is about 38mph.That means until you hit about that speed, the car will be MUTTY. Unless your suspension is lazy and you manage to get into tire-spin, in which case the whole pkg begins to be MUTTY.The problem can be band-aided with gears and TCs, but that brings along other compromises. 4.10s would bring it to 32mph@4500. I higher stall TC will help the launch. Etc.
With a teener you have to be somewhat concerned with getting up to speed. So a lessor cam would be my choice, along with on-the-edge Dcr, and headers for sure.To go with the smaller cam I would hook that baby up to a wide-ratio, loc-up-TC,904. The 12% more take off TQ will allow a tighter TC and the loc-up will help keep the revs down in top-gear. And the torquier cam will fill in the midrange nicely.
My carb choice on a teener would be a spread-bore, on a spread-bore manifold, with the smallest primaries I could find. I like metering-rod carbs.
If it was for me, I would choose a 218* to 225* cam.I would set it up with a thin(.020) headgasket, a very tight quench(perhaps .025), and shoot for close to 8.8 Dynamic cr. Then if I couldnt stay out of detonation, I would swap in the .039 FellPros.The FellPros will knock the Dcr down about .2, and increase the quench about .020. Ignition tune would have be sharp. This will require either closed chamber heads or custom pistons, or a lot of machining. I would go with custom pistons or pop-ups.
I would have way more torque off the line(at the same rpm), and a much more funner car(as opposed to that 509cam). If its not fast enough, I would lighten it up . 100 to150lbs should be easily doable , and is easily worth 1 cam size.Built this way, I would leave whatever gears are in there for a while.
FWIW, My 2nd cam for my 360 was a 223@050fast-rate. That was my favorite.Dont forget the ZDDP!
If you put that 509 in there................................... I will come to your house and spank you! lol.

It will for sure "sound" healthy, but I think he is on a budget, and I can certainly appreciate that, but having to do it twice is more costly IMO.
I am always up for other options as of right now i have a low of people telling me to get different carbs with out even knowing what i got and i have a 727 that's going to be behind it not a 904 and and the only budget im on is that i want something and i don't have the money for it ill save till i got it ot can fine it and the only way i will do this twice if it blows up and i need to do it again im really upset on how this is going i asked for advice on carbs and intakes and everyone is telling me im doing it wrong sure im truly doing it worng it will not work and ill be very disappointed ya sure but everyone i know here three co workers one being my uncle and and all three bigger mopar guys then me and know alot more then me gave me this stuff said it would be a great motor and everyone would be surprised this is my last post till i get the car driving then ill post a pic video and whatever else you guys want then i am leaving this site say what you will whatever i was looking for advice and really didn't get any on that thanks everyone its been fun see you in a mouth or two
Carb and intake. Weiand 8007 Action Plus, LD340, Performer RPM. Carb, I could only guess as we have no idea where you are headed with this build. The only thing we really know is the cam.
Sorry you don't like what folks are telling you, it's all meant to HELP you.

My post is a been there done that with exactly what you have... Exactly.
Fwiw, I made the switch from a TorkerII-340 & a 630 AVS to a LD-340 & big TQ to a RPM & 750AFB. I have mixed and matched and fooled around with the combos switching parts around. (I love to tinker)
Use a 650 Holley DP 4 corner idle system on a RPM-AG with a MP distributor and Chrome box.
Been there, done that, still have most of the parts.

You need to understand what you have and what you are going to do with it. The number one very wrong thing to do is mismatch parts. That is why folks are asking about your heads, your gears, your trans, your intended use. They need to match to work properly, together.
Over cam'd engines are no fun on the street and even worse with improper gears and supporting trans mods. You'll get beat by 4 car lengths by an old lady in a walker with tennis balls for traction.
Guess why all the comments in this post exist? Because been there, done that.

Well, you are obstinate.
Our way, is the safe way. It gives you options. And bang for the buck.It can grow with you.
Your way is an almost a guaranteed do-over.
So bookmark this thread, so you can review it at a later date, when you need to spend more money undoing,or changing, your combo.Start saving asap.
If you insist on that 292/509, in your teener, you're gonna have to wind it up to get something out of it. You are going to need some really good anti-pump up lifters, some really good springs,custom pushrods, and adjustable rockers highly recommended,if not as good as mandatory.
And if your heads give up early, well, theres always, do-over...............
If the lifters pump up and crash the valves, theres always do-over...................
To survive the rpms,theres oiling mods to be done. If you skip those, well, theres always do-over...................
And a deep pan for the extra oil it will need, cuz without it, um.....do-over
If you throw a belt and dont catch it; do-over..............
If your laziness in punctuation is also apparent in your set-up and maintenance regimens....do-over
Hi rpm comes with a lot of forethought,prep. work, and dedication.
Dont forget the ZDDP!

I dunno what you're so bitter about...I saw at least three people who gave their suggestions on what carb and intake to run. How many opinions did you expect to receive?
Furthermore, the folks who've tossed in the suggestion that you're likely to be thoroughly disappointed with the performance with your chosen setup are only trying to give you firsthand experience so you don't have to waste your time and money-two commodities which all of us wish we had more of, and surely you'd much rather be driving and enjoying your ride, right? but, all we see are your caustic rebukes about how your uncle and two other coworkers who call themselves Mopar guys said it'll be a great combination, therefore everyone on here must just be haters or something...lighten up Francis, you'll live longer...longer to enjoy your Mopar.
Best of luck man
You are getting good advice here Dwak, the guy you "trust" at work is offloading some parts on you. Sounds like he means well, but overcamming a teener is only going to lead to a dissappointing performer. Everything has to be matched up in an engine or car build to get the most out of it... Compression / Cam / Heads / desired RPM range / converter / rear end gears....
That 509 cam would be good in a 360 with 10:1 compression and good aftermarket heads, put it in a stock headed 318 and you will have a dog under 3500 rpm.
I would suggest something in the upper .400" lift range with mild duration figures, maybe a converter and some 3.55 gears = will run circles around a lopey idling 318 build. Good luck, take some good advice from those that have been there / done that.
