cost aside, do you guys actually believe the new hemi is even equally as good as a LS??? my local track has a fox body with a turbo'd 4.8 running in the 4's... I can't say I've ever seen a new hemi that was even remotely fast?
Yes, eagle heads can flow we'll into the mid/upper 300's, 6.1 heads high 300's low 400's, apaches well into 400's just going off the top of my head. Hell, the original 5.7 head can get we'll into the low to mid 300's when CNC'ed. The blocks are strong, guys pushing them to over 1000 hp (but they suffer the same problems as the LS engines do with boost, they like to lift cylinder heads with lots of boost).
The major Achillies for them is the stock pistons are weak (thin ring lands) where the LS pistons seem quite abit more robust in stock form.
BES handily won a recent Engine Masters with a 5.7 based HEMI using 5.7 original heads. The 2nd place engine was an LS but was down quite abit on power compared to the BES HEMI, so yes a GenIII HEMI can run with an LS with no problem.

Thats just it... you can re-cam a junk yard LQ4 or LQ9 (6.0) and throw the L92 heads (big port) and make 500HP, THEN add nitrous it for 800HP... all for around $2K... freakin crazy... Meanwhile I can sell my 340 for $3-4K that would pay for the LS swap and then some... Just thinkin out loud I guess... I never liked mixed breed cars, but just seems you cant beat it for the money...
I will agree that LS's are impressive...but it's nowhere that cheap and easy to make 800hp with an LS. Yes...that can be built fairly cheaply....but not that cheap. How do I know?
My brother owns a fairly popular speedshop that specializes in LS performance and swaps....one of the cars that he built a twin turbo setup and did the tuning on just won a Wally at a fastest streetcar race in pomona a few months ago...so he knows his stuff, and it aint that cheap. But it is impressive....I see lots of 5K dollar LS's that run mid 11's because they have good parts. If you spray 300 hp of nitrous with a stock plastic intake be prepared to pick the pieces up off the track and hope your engine doesn't ingest much of it. I do appreciate what your saying....and if you want an LS, go for it...you will get a lot of bang for your buck! 
Oh....I' finally got back to working on my own car...A 440 Mopar with an LS Computer/EFI/and coil on plug ignition...

Dumb question, but why not a 3rd Gen Hemi? They seem to be the next best thing.

They don't have the tuning support the LS motors have either...you can find LS tuners everywhere. But I like to be different....so I'd do the 6.1 hemi with a LS computer  .

True, however if I'm sinking any amount of money into a car, I want an aftermarket EFI system anyway. I've played with a couple of factory efi computers and I don't care for it and certainly wouldn't swap one in with the intention of retuning if after.

Here's the best way to go and put the mopar in the garage.A buddy's step and e will sell as a roller 2. -------------------------------------------------------------------------------- 79 Capri "Rosa Belle" The car is currently at Gary Rohe Race Cars getting a complete new c/m 25.3 cage and rear suspension...that will be certified to 6.50 at 3600 pds. The motor is a completely fresh BES 434 with wilson plate and fogger both flowed by Kevin Neal....With Coan full case glide with all the trimmings. The entire suspension(coil overs and struts have just been replaced with drop spindles etc. The car is also being rewired by Gary Rohe. This car is a multi time KOTS winner as well as multi time limited 8.5 winner. The car will be up for sale as soon as it gets finished and gets back home.. It will be available turn key or shell roller or in whatever configureation you want(fuel system..wheels tires....shocks and struts etc....just pm me how you want it and I will get a price together.....I also have a 2012 30 ft. storm enclosed trailor that i will make a pkg deal on...Here is video of the car in case you dont rememmber it. I believe the car has been consistant 1.20's 60 ft and has been 5.20's in 1/8 mile and 8.30's in 1/4 mile on one 1 kit with the old cage and suspension. http://www.youtube.com/watch?feature...&v=1ud74LTeDu0

The only cars that don't phase me anymore seeing frankenswaps in them is fox bodies, mainly because they are such a bastardized cookie cutter car and they mean nothing...I cringed when they had some nissan motor in a mustang in fast and the furious (as gay as that movie was- and that was the icing on the cake for the entire series), just like I would cringe seeing a chevy motor in a mopar.
I have to say, the new hemi can be done for quite cheap- maybe not as cheap as an LS motor, but the potential for them is just as much if not more for the LS. I would seriously look into one of those if I was you.
If you can't make the brand of the bodystyle run fast enough, buy a different car- I am a mopar guy through and through, but slovas, slomaros, and shovelles are all good looking cars that would house an LS motor much better then any duster
Well said! For me Fiat has to release the encryption software. Once this is done sky the limit.

Not sure about Fiat releasing it BUT the guy I would go to for Diablo Tuning said that they are already tuning 2011+ now. 2006-2010 has been available for years.
But if you're gonna do a swap why bother with a Mopar PCM go with a stand alone EFI system.
