I drive and test carbs weekly on my stroker 470 which makes around 700 lets say based on my recent 1/8th mile et's and mph. A blast to drive but I've been doing this since the late 80's and if you are not pointed in the right direction when you stab it, things can go REALLY wrong..........Based on your questions I'd say if you had a 450-475 hp 440, you'd be ecstatic...........

Heh heh heh........

You’ve just discovered the big flaw that’s in many engine building simulation software programs.

I built a 446 and a 493 that were very very similar to each other besides the displacement.

On several engine sims the 446 showed higher output.
On the real dyno the 493 was clearly better...... and not by a small amount either.

Ah yes, a polemic and soft pedal troll joined the board to ask us questions, then tell us the answers. I’m not the only one to notice, just not as nice as others about it. We can dunk your head under the water, still you won’t drink.

It appeared when you first arrived on the scene you might put together a nice build for everyone to follow. Now it’s painfully clear you won’t get beyond “telling us how it is.” Reminds me if a kid a few years back that asked about an MP cam. He got his info, then lit into 20+ people about how they were messing up by not running his choice of cams. After doing exactly what you are right here. Good luck with your build, you’re gonna need it.

Ah, more entertainment!

Your first build is fine, I still say do that + change the intake and have fun.

Cam operating range is marketing 101.

Yep I have found the same as you on my old dyno, was trying to show the rpm difference ,same cam & more cid. & as you know it is just a Sim.:)

On the other hand if you wanna be hardcore about it, here's what we used to work with. Decide how fast you want to go and install the appropriate combination of parts. Poof. Done.
Really you could just do one of these.

People complained back then (people will always complain)
but there are times I could swear we were more......productive....not the right word but close as I can get right now.

Build a combo that sounds cool and go out there and flog it, work with it.

Zippy, I remember that guide! I like how the combos were all about how fast you wanted to run at the track. Before all the dyno racing began, it was all about manning up and running down the 1/4. Those were some good times. I went for the 509 cam combo and man I really thought I was hardcore! haha

Now we have so many options by comparison, its nuts.

10 years with the 484 cam combo. All I could afford, and no regrets!

13 second combo, ran 12.50s after some effort, and to this day I swear a 12 second car is still a very sweet spot to be in for just general street strip badassery.

Zippy, I think you led the OP to figure out the answer to his question in the other thread regarding operating ranges.

Yep, something to be said for a simple ring and bearing 440 rebuild with cam, intake and headers. The bang for buck is maximized!

I sure hope so, B. I'm trying to be friendly and honest to Nick.

I feel sorry for anyone coming up in "the information age" because the assumption is... manufacturer information is always correct.

Big fan of your Charger and love what you've done with it.

Serious questions here.
1. WHY 550hp? why not 525? 600?
2. What is that fastest vehicle you have ever driven?

Most street guys that say they have 12 second cars can't run 14.0 seconds let alone in the 12.s,
HUH Dominic
Some people listen and learn and get faster and faster like Dominic did, dang his hide anyways
What did I do and help make anyways
BTW, we all NEED to and should help others in this sport if we want to continue to be able race at tracks

YOU Cab created a MONSTER and I'm very happy with that, neighbors, not so much............ I drove a guys turbo Probe and swore it was at LEAST a 13 flat car..........NO where close......We all started somewhere............

So anyone that doesnt want to even attempt to help, or tries to be condescending stop replying. 550hp/600tq is just a general combo i want, if i get 525 hp and 580 tq id still be happy. So can someone help explain operating rpm. I understand that theyre not the end all be all of picking a cam, not even close. I have one simple question, since this thread was meant to be simple and it wasnt, ill just make it simple now. Does a 2500-6200 cam require more throttle when letting off the clutch? Would it be alot more throttle than a smaller cam? (I guess two questions)

To answer your question, no, you shouldnt have to rev the engine excessively or slip the clutch or anything like that pulling out with a 2500-6200 operating range cam.
I run a .528 solid cam in my stout 440, four speed,3.31 gear daily driver and it has a similar rpm range i believe. Great street manners, easy driving in rush hour stop and go traffic. Couldn't be happier with it.

Best thing i can suggest, is to use the google custom search bar at the top of the screen and do alot of searching and reading. That's what i did, and these guys knowledge and experience didn't steer me wrong.

I would not worry about getting off the line with something like you are wanting to build. I believe with a stock stroke the advertised rpm ranges on the cams will be close. So will the gearing and converter recommendations.
I honestly don't understand why this thread is almost 3 pages long. The op is asking for a really simple recipe.
A stock stroke 440 with stock steel crank, stock (w/arp bolts)rods or new h-beams, and a flat top forged piston close to 0 deck. You'll want a piston with 2.05-2.067 compression height.
Trick Flow cylinder heads,
Any nice hydraulic, or hydraulic roller with anywhere from 230-245 duration and .550 valve lift is gonna get you 525-550 horsepower with tons of torque. `And you will live happily ever after.

Sorry to say it looks like B may have been incorrect, the pointers didn't help. I really tried

Books have a big advantage here in that they give focus....
The reader gets input from only one expert, and in only one style of communication. Here you can sometimes get a consensus, but folks seldom totally agree 100% on every little detail.

Instead of 27 threads with the same stuff I'd kindly suggest read up first and ask questions later.

Not sure if anywhere in this mess it was communicated that a 500 CI stroker will eat duration. The cam that might have a 3400- 6500 operating range in a 440, might drop maybe by 1000rpm in a 500 CI.

Nick, the marketing guys for the cam companies list the same operating range for a cam in a 383-500 CI, it doesn't work like that.

The cam in my 520 I think was rated from 3500-7000 rpm.
It pulls down to 1800 just fine, and like any other vehicle, when you learn to drive it, can be done efficiently.

When you have big cubes,you will have more torque than you need.

You also will get a lot more need for good traction and unbreakable drive train parts Trust me on this, been there, done that
