I’m getting a pair of JBA long tubes here soon in the upcoming months, I will only be Dyno tuning once before I’m done with mods for a while so I figure, hell why not a cam shaft! I like the 274 sound and performance gain, but I’m daily driving a 2017 challenger TA Plus 5.7. This way I’ll only have to Dyno tune once.
I looked around and saw the 392 cam is a nice one, the comp 270 and 266 I’ve heard good about as well. I’m not sure which ones I would be better off with. I’m looking for low-mid range but I do want to be able to tell I have a cam sound wise.
I can’t find any recent info on this as most are bumping 5.7 to 375-400 and that’s years ago, mine is making 375 stock.
What would the best performance cams be for a daily driver? I want the most performance gain but being low-mid range rpms. Also, what all would be needed for this swap? I figure I’ll need a phase limiter and springs atleast for any cam I do.
Thank you!

Contact MMX, OST Dyno, or Jay Greene for cam options. Can't go wrong with any of them.

If you are going to cam the 5.7 you might want to also think about going with a 6.4 manifold as well. Do a search on the forum, plenty of guys have upgraded the camshaft and manifold.

BTW this guy shows what a 6.4 cam (just needs upgraded springs no limiter or lifter swap required), intake, and headers can produce.

Also, you can check these sites for dyno numbers (RWHP not engine HP). BTW the 5.7 puts down roughly ~330 RWHP.

I am saving up for the "Big Daddy" cam over at OST. I am going to start with just s tune first, (hopefully around May) then long tubes maybe later this summer with a retune and then next year, the cam, ported heads and torque converter. Hoping for 500 WHP out of my 5.7l

I thought the big daddy was for the 6.4, now that’s an option lol

$12k...isn't a 6.4 crate like $8k...probably less labor to swap out as well?
Lot cheaper to do this than a cam with long tubes. My cam swap with top of the line upgrades was pushing $6k and that was with me doing the labor. I pulled the heads, ported them, and swapped lifters too. That's why it cost as much as it did.

Every time I mention a crate motor swap for my 5.7l for a 426 (the 6.4l is junk if you want to eventually want to run boost) I get shot down so I figure I can build the 5.7l to out perform a 6.4l and then if I want, after that boost, it because it's piston design is NOT garbage.

I am sure you know this already...but honestly, just throwing a SC on the 5.7 ~$7k you can out perform a 6.4. Not much labor involved to install one and still makes good power with the stock exhaust manifolds. But $12 for headers, cam, heads, and converter on a 5.7....you still won't get the power levels the SC running 8# of boost can provide. I would love to do a 426 but man the cost just makes me look for a Red Eye.

All I have seen is 6.1 and 6.4 engine punched and slung to 426.
Hey chally, would I be risking anything driving with untuned headers and a cam for a short amount of Time? Install is only 1500, Dyno tune is 550 and 125 per hour on top of 550. Overall I think I’m looking at 4-5k overall. Installing jba long tubes (700) by my self, running open headers. For a Dyno tune I need a diablo tuner and unlocked pcm, but I was wondering if I could save a little bit and put off tuning for a week or two until a few extra paychecks hit. I doubt theirs a payment plan lol

Also, how does this sound?
219/227 112lsa 110incl 587 lift cam
That was what my shop quoted, I have no clue what that is or if it’s goods lol. Said I could gain 60-80 HP with it and long tubes

If you want to go without a tune, best option is the 392 cam. It's still risky because you've increased air flow w/cam and headers without increasing fuel flow.

When it comes to mods, the most I have seen a cammed FBO 5.7l Hemi hit is 418 RWHP. 99% of cammed FBO 5.7L hit between 375 to 410 RWHP.

The cam you are being quoted is similar duration to a 6.4 cam but a little more lift with a similar LSA as a 5.7 which should give more torque at the bottom end by sacrificing a few ponies at the top end. I am not a cam guys so other than that I can't say how good the specs would be for your application.
