I went with the comp cam 270. Most people going comp cam go 270 or 274. The 274 is a beast to tune. The 270 Offers mid range power gain whereas the 274 offers the gain at a tad bit higher RPMs. The folks above are correct, It was expensive to do with lifters, push rods, mds delete, phase limiter etc. however, it pays off when you think of it as staging. The final product will all add up. Hit me up if you want more info, I have sent a couple of guys my setup with everything you need on an 8 speed 392 cam swap. Part numbers and what it runs about around here in Chicago. If you can do yourself you will save a lot of money. As far as reliability etc it really comes down to the tuner. Again it’s a lot of money for the gain alone but if you think of it as staging it’ll be worth it at the end and the sound is amazing, def not like an old school muscle car but the lope is there.

I'm not too put off by the cost, because the gain in performance and extra reliability by strengthening the top end of the engine will be worth it (so long as the tune is good).

I've never torn apart and wrenched on an engine, let alone the Hemi, so while I'd love to do all the wrenching myself I just don't know what I'm doing. Don't know anyone around me who speaks Mopar that could help either. Doesn't seem like the type of thing that I should learn on the fly.

So far as the sound, I'm fine with a little bit of chop, but not to the point that it sounds like the engine is going to stall and the whole car is shaking me to pieces at idle.

MMX is looking real good to me right now, they have a shelf grind Max Effort cam (requires springs, but that's fine, I was replacing them anyway) that adds about 100hp to the crank without sacrificing driveability or low end torque and it comes with pre-determined tunes (2 tuning credits) for only $350.

That’s awesome man. I’ve read good things on the mmx cams. I’d double check the hp gain though just so your not disappointed. Most dyno numbers show around 35 to maybe 60hp to the wheels gain on a cam swap alone. There are several threads on here with numbers and some good videos on YouTube regarding actual gain from a cam swap. The range seems to come from tuning, and maximizing while maintaining safe function. Whoever you decide to go with I’m sure it will be awesome. Look forward to hearing what route you went. Best of luck.

That's about what MMX advertises for their NSR cams, although they do recommend a larger throttle body, a ported intake, and long tube headers for best results. I was planning on all of those things as well. Their dyno videos show a FBO and max effort cam setup making 500 wheel. I'd like to think that that isn't just hype!

I know the $ per horsepower isn't nearly as efficient as going supercharged, or even upgrading to a used Hellcat (which may still have a warranty, or an extended warranty), but I think it'd be cool to have something special and almost unseen these days: a large cube, naturally aspirated V8 with a cam making close to 600 crank horsepower. Of course, I also still have to think about driveability and how the power band is affected.

I wonder if it would be worth the extra 2 grand to get a head port and polish done? As far as I know these heads already flow extremely well from the factory, and too much flow could actually hurt power gains.

I’m with you on having something you put together. I love feeling the change in stages. First thing I did was long tubes catted midpipe and first tune. Which as you know that first tune is pricey, getting the pcm unlocked etc. then I went cam springs lifters push rods and second tune. It’s nice feeling the difference in between stages. At least I like it. Others like it all out the box and that’s totally cool as well. Whatever your preference is, is the way to go. You get to make it your own. Your right I’ve read a lot about the stock heads and many people say the stock ones are impressive.
I’m looking into a stroker kit, ran into a guy with a 426 and wow was that impressive. He also had a pro charger though. He said that was the last thing he did. Have to admit that 426 along with the winding from the sc was so nice. These cars are pretty well built from factory, tons of owners just add the sc and are done with it and it’s still pretty impressive. That’s why I like this forum, you have guys doing all sorts of stuff. Fun to read and keep up with.

There’s no right or wrong way. Sure you can stay stock. Sure you can upgrade trims. Sure it’s expensive. But is it a waste of time? I don’t think there’s a right answer to that. Some people aren’t after numbers and would rather build their own car as opposed to going factory upper trim. Some have the money for a hellcat but would rather build another trim. To tell someone what they should do is completely irrelevant. What may be a waste of time for someone may not be for another. Non challenger owners may say the same about our cars; why so much power, why so much for a two door etc.... to them it may be a waste to own a challenger. The point is to each their own. You can do whatever you want with your car. Leave subjective matter out of it and help guide fellow owners objectively.

Sorry, that was meant to be more sarcastic, I should have been more clear lol. Unfortunately what you see a lot on this website is a lot of people telling you not to waste your time which I find lame. I agree with you and I’m on the same page, I’d like something to be mine. I’m not looking to do mods because I’m trying to become a Hellcat, I would just like to build up the car I love. Mines just for fun because I can and if I can get I to the 12’s (N/A in Colorado at 5700’) I will be very happy. I’m looking at learning some more along the way.

That is awesome man. No I get it completely, tons of people saying don’t do this because it’s a waste of time and that may be for them but not for another. What I do like is when people give objective advise such as one part over another and the whys. That’s good stuff. Good luck on your build
