I am deciding to make yet another thread, since obviously most people wont read and reply to each post on my other threads. So to keep it simple, first heres the link to my original idea: Original 440 build Fyi it will be a manual 5 or 6 speed, but most likely a 6 speed (tko600 or t56) 1. I have since decided to get the SD intake, and most likely a hydraulic roller cam. 2. If i want to make that power and torque with essentially everything the same, would i need to stroke it?3. When it comes to a cams operating rpm, if its a 2200-6000 would i have to rev higher in first gear to move it on the street compared to a 1800-6000? Thats what i need to really understand.4. Any suggestions on hydraulic roller cams ( for w/ a stroker or w/o a stroker)? (And preferably with an operating rpm that begins anywhere from idle-2200 and goes to 5800 or more, if im not wrong on how operating rpm works)5. I may edit this post (and italicize the changes) if i forgot to mention anything 6. What does everyone think about the lunati 60311? Would it work good with either the stock stroke or stroker? Adv duration: 270/278, duration @.050: 219/227, .515/.530 lift, 112 lsa/106icl

Nick, as you know, I run the Lunati 60303 cam
440 .030 over Oob Stealth heads .017 below deck, Cometic .027 gaskets for quench 10.2 Compression ratio Eddy RPM Holley 850 DP Headers
833 4 speed, 3.55 gears, 28 inch tires.
Cam was degreed, came in at 106.75. (Was supposed to be 106). I ran it that way for a year or so then advanced 2 degrees to 104.75-----I was bored, don't get too caught up in this detail.
I can pull away from a stop at 1000-1500 rpm as long as I'm light on the throttle until 1900 rpm, then full throttle is OK (and of course will fry the tires).
What I CANT do is pull away from a stop at less than 1900 under moderate or heavy throttle----if I do the engine will lug. It's all about split second timing of the clutch vs throttle--that's all.
Similarly, I can cruise in 3 or 4th gear at 1500rpm, as long as throttle is LIGHT--if I want to accelerate from this condition I either stay gentle till 1900, or downshift.

Thank you for your reply, and thats why i wanted the 60303 cam, but was told it will limit my numbers well below the 550 hp mark. What are you making?

And yes, I think if you are after a true 550hp at the wheels below 6000rpm, you will need a stroked motor. (Unless you go with a power adder of course) And no, sorry not 550 at the wheels (i wish). At the crank.

I've never dynoed it, so anything I state is a guess. If I give myself a WIDE range, low to high, I would say
425-525 flywheel hp........I'm sure reality is in there somewhere...LOL. Lol, any guess on the torque, because id be more than happy with 525? (assuming ur on the high end lol)

Have you driven a 440 before? Chances are you could put that cam in a basic 10-1 short block and slap on OOTB or preferably mildly work heads and have a lot more fun than bench racing like this. It’s really no sweat changing the cam later if you find it doesn’t do what you want.
Unless you hit the mega millions or poweball you might find dollars spent on a mild almost stockish build go further than going hog wild right off the bat. You need to find a local machine shop you can trust or spend the money you’d otherwise spend on fancy stuff shipping in mopar specialist worked over equipment.
I want my fair share

And id rather not do trial and error starting with a very basic build. Itd be way cheaper and simpler to figure everything out in the beginning. Thats why i have asked so many questions and made so many posts.

You clearly don’t have the experience in the hobby many have on here, evidenced by not understanding cam selection. HP level, RPM range, etc are not the real deal. People have given you the gospel over and over and over. The only question left to ask at this point is will you accept it?

People have given you the gospel over and over and over. The only question left to ask at this point is will you accept it? And id rather do trial and error on forums than on my car. Every cam suggestion i have gotten starts with an rpm range at 2500 or above. That is why im asking questions. No i havent built an engine. Why do u think im here. Youre right i dont have the complete knowledge on every aspect of motors. thats why im here. I even asked someone to help explain to me how operating rpm ranges affect performance and street use. So congratulations you pointed out that someone that has asked alot of questions is not an expert. Are you proud of yourself? Its not much of an achievement. So are you going to help answer my questions or continue to exert your superiority of engine knowledge? If youre not here to help dont respond.

Yep, you don’t learn. Still hung up on same stuff. You might try a book. It won’t talk back when you reject it.

Nick,
You are filling in the blanks for the variables that affect your specific issue.
Like this...
You want 550hp You don't want to spin the motor past 6000
Those two specifics dictate a cubic inch requirement that is likely higher than 440...likely.
Now you add in the requirement that it be a stump puller (my words) off idle
Now your REALLY making things difficult, if not impossible.
Does that make sense? But strokers greatly increase low end torque correct? So its very difficult to have a good street driving 550 hp 440?

Well "good street driving" is kinda vague and people define it differently, but you seem to be caught up in the fact that a performance cam won't pull like a freight train from 1000 rpm. It won't. But it's not a big deal, at least the way I define "good street driving". When it comes to camshaft selection, IF max RPM is a big factor for you (that's OK...MAX RPM is a big factor for many people and many engines!!!!!). Then a good selection technique is to select a cam with a max powerband that matches your max expected RPM. After all....why select a cam that's good to 6500 when you never expect to use it? The Lunati 60303 has a max powerband of about 6000, it's therefore a reasonable choice for you BASED ON MAX RPM. Now with that comes a minimum.....call it 2000. You have to live with it (at least in terms of THIS cam), but a powerband that starts at 2000 is pretty damn good, for a performance cam. If you select a cam that's lower....you're rapidly entering the realm of low-PO / stock cams and you simply are NOT going to make big power numbers. For example, you might find a cam whose powerband starts at 1500, but it's not going to make big power at 6000, and it's not going to reach your 550 hp goal.
