What Are Some Mods That You’d Recommend For A 5.7 Hemi To Aquire More Torque & HP Enough To Beat A Stock 6.1L Or Possibly Even A 6.4 Without Superchargering Or Turbocharging The Engine

A Charger with a naturally aspirated 5.7L is not going to beat a Charger with a stock 6.xL. Forced induction is required for that.

If you don’t want to s/c or t/c it, go with some laughing gas. Not as streetable, but it’ll get the job done assuming tune is adjusted to handle the NOS.

Cam, exhaust, intake are all good 5.7L mods, but they still don’t equal what the 6.xLs are putting out stock.

The Eagle head 5.7s with the 8 speed are right there with the 6.1 cars in performance. Both will do high 4-low 5 second 0-60 and 13.4 1/4 mile times.
The 6.4 will need a lot of tinkering to match.

Depends on the 5.7, having two eagle engines you should know that.

The whole reason for the stretch to the 392 was to distance the SRT from the R/T power wise. For two years (09-10) the 5.7 (370hp) was only 45hp down from the 6.1 (425hp). Eagle heads are as good as 6.1 heads even with ever so slightly smaller valves and in some ways better. A healthy cam will get you part of the way, but you have to remember the SRT isn't just more engine and cam, it's a total package, which includes better gearing. I just watched a mildly modified 2015+ Charger (stock cam) smack the sh!t out of a mildly modified 2009 SRT Challenger (also stock cam). You won't hang with a 392 without a displacement change or boost.

i have seen some 5.7s hang with or even beat a stock 392 with full bolt ons (intake, headers, cold air) a strong cam and ported heads. some other things you might want to consider are upgraded gears and exhaust. these 5.7s have made easily over 430+ whp with this setup. personally, im only going fbo with the hrt stage 2 cam and ill probably make 400-410 whp

We all know anything’s possible, especially with enough money, but this is the really real world. If you expect to be able give any random SRT/SP found on the street a run for their money, go forced induction or upgrade to the bigger engine yourself. That’s the only sensible approach to the stated goal.

Otherwise you will spend thousands and thousands of dollars on mods that will not only void any powertrain warranty still remaining but also require a perfect scenario to work out in your favor at the moment it’s needed.

Are you willing to spend $10K on the possibility of getting lucky enough to find a bone stock 392 driven by a noob that’s willing to run em at that instant?
