I was looking on a website some of you may be familiar with already called shopHEMI.com. I priced out the 6.1L HEMI 426 at 17k. This engine comes with 585 HP with 560 Ft-lbs. of Torque, a 30 % Increase in Torque and Power over the stock 6.1 HEMI at 160 mph. Now my question is that would it be cheaper to buy all the bolt on mods for the stock engine and get that kind of power out of it(which is very possible with forced induction), or would it be aroud the same price to just buy the Arrington 426 HEMI for 17k? If the prices are close then you might as well just buy the motor, or at least that's what I'd say, but I don't know how much it would cost to get that kind of power out of the stock SRT 8 with the 392. Let me know what you all think. Thanks...:fing02::thumbsdow

You would need to know exactly what parts are going into the engine before you can compare prices.

Power Ported Performance is also a sight supporter/vender, run it by them.

The stock SRT does not have a 392. The 6.1 is around 373 cubic inches. I have an Arrington 392 block with PPP cam and heads in my 300c, and this engine is a work of art!

I just wanted to know if I added every bolt on possible except forced induction, could I get that power for a better price out of the stock 373cu SRT 8 engine block.

If you get the 426 you'll probably have a much more reliable motor to make that kind of power. To get 585 hp out of a 6.1 you'd have to go with NOS, which is considered forced induction. A cam, heads, exhaust and all the other bolt ons will only get you to maybe 450 rwhp if done/tuned right. You could probably get to the 585 with heads, cam, all the bolt ons and a supercharger for around 10k, but its not going to last as long. You could always go with a nice forged 392 and supercharge that. Probably looking around the 17k range and you could have the potential for 700 rwhp. I've heard the 426 isn't the best choice to supercharge, needs to be bored too thin.

Thanks. I don't want any forced induction. I like it all N/A.

You can do a really nice 426 (actually 423 or 420ci) setup for about 12k. I think!!

Theres no resplacement for displacement!

Anybody paying $17k for a stroker is getting it up the a$$!!! $8-12k at most!!!

Heads/cam/intake manifold/throttle body/diablo cmr/pulley/exhaust/headers/CAI= $7k approx= 480rwhp=550 crank

Agree with the first part

I agree with the first part. My 426 was around 12k with half shafts included out the door and tuned.

As far as the 480rwhp with heads, cam, cai, headers, exhaust and cmr that depends on the dyno you are on.I have seen some around there and some around 450rwhp if they go on the (superflow) or (Mustang) dyno like they used with my car.

But yes you are taking a nice plunge job paying 17k for a stroker...

Where did you get your work done? How much power is your car making (to the wheels) with the 426? Any driveability issues?

Nevermind... found it via search.

I assume you're still very happy with the setup?

Yes very streetable and it will make the magical 500 plus HP on a dynojet if I ever feel the need to put it on one.

You should not need to pay anywhere near 17k for a 426 setup...

Pretty much the route that I'm considering. Already have all of those upgrades along with a ProTorque converter. Everything is fine but... I always want more! May add a Vortech supercharger and then if anything happens, I'll stroke it. Hum... that didn't sound right :)
