Like Jeff said, this is entirely possible, but the cost would be more than if you did some well selected mods. to your current 5.7. Probably the biggest advantages to the later Hemi are the bigger heads and variable valve timing. In the long run, if you later chose to mod. it, you'd have more potential, but the initial cost now would be higher. In any case, if you're like most of us, your pocket book will dictate how much you end up doing.

Over the past 6 years and about $4000 on each, I've increased performance (nearly 100 hp. more) and fuel economy (about 25% on the WK/20% on the LX) on both my Hemi vehicles (modded identically) with just a few well chosen mods. First, for the WK, you have to get rid of the stock exhaust and get some sort of header and 3 in. low restriction cat. back. Second, you have to either advance the stock cam or do like I did and get a relatively mild aftermarket cam (I advanced mine a total of 6* on the WK and 10* on the LX) to get a better flow through the combustion/exhaust tract. If you're going to do any off roading, you may want to just advance the stock cam, as an aftermarket cam, installed straight up, will kill some of your bottom end torque. If you go too radical on the cam timing, you'll adversely affect driveability....but it'll really sound neat. You can look at my signature to see most of the mods. I've done. It's not all current, and you should know that you'll definitely have to do some transmission work too to support the added power. Good luck on whatever you do, and if you have any questions, feel free to ask.

You may want to go over to the WK SRT portion of the forum and see if anyone has some for sale.
