If you think about the cost of the parts that you'll need to do a decent build, it'll definitely be in the thousands. Then, consider the machine work and paying for a quality job to a decent engine builder, again, in the thousands.
AEV's Hemi kit for $5,300...enough said.

I would love to have the 5.7 MDS hemi. I bet the MPG wold smoke this 6. I would rather have a diesel though.

I believe that. The mpg isnt that good to begin with on a JK, add all your mods and it only gets worse. If you have an engine that doesnt have to work as hard to pull your vehicle around the mileage will be better. The hp/tq you will gain from a v8 will more than make up for the added weight.

The MDS is pretty much a joke and most people using a programmer with them were begging for a way to turn it off. Superchips delivered, the power went up and MPG hardly suffered. The 5.7 with the 6.1 heads and MDS disabled will provide nearly identical MPG and a load of additional power compared to stock with MDS.

Any shade tree mechanic can have the machine work done at a fair price, and buy the parts at their timing and put it together in such a way that not only do they know what exactly is in it, but can diagnose easier what went wrong if something did.
The reasoning you and others are suggesting is basically this, don't bother to modify your suspension until you get the correct wheels, 42" tires, 5:68 gears and and a complete EVO system with long track bars, etc.
Think about it, what happened to all the fun of personalization, the differences in our Jeeps? We'd all be expensive clones of each other and the "Jeep thing" would disappear off the face of the earth.
No thanks, I'll personalize thank you.

Since there are no race/power options, not even NO, how can there be any rumors about a weak bottom end?

When I ask the local Machinist about this building motor he rolled his eyes and said get a decent base to start with.
He had rebuilt a couple of these motors and made the bottom end statement.

Its not a good engine to start a build with. You could do it if you really wanted, but like others have stated already the cost to build it up to get similar numbers out of the options you are sick of hearing, will be close. There are some fast or powerful v6 engines out there but they cost as much and sometimes more than a v8. You would want a 90* v6 we have 60* v6s. Again if you dont like the other options that are out there because of the price, you wont find it any easier with your stock engine. The amount of time and money to do the R&D, you could already be driving a Hemified JK.
A cam, stroker kit, head work is far more beneficial in a 60 degree V6 than in a straight one. Yes, it is easier to build a V8 and its about the same money, but its a good thing we all have choices and differing tastes or all our wives would look the same and have the same equipment. Then again there are some guys with high maintenance women who cannot afford them so why not high end mods, eh?

It's about the most bang per buck there is, and combined with a little head/valve work and we can really find out if there is a weak bottom end or not.
