Default 5.7L verse 6.4L Hemi Upgrade

Hey Guys,
I have a BDC and researching motor/axle upgrade. Question I have is which motor and why?

I've driven a 6.4L Wrangler not BDC and it's amazing. That being said I have heard from several folks that 5.7L is great as well. Some suggest that the 5.7L is better for wheeling.

Thought I would put the question out there to hear real world advice. Thanks.

Best,
Johann

Sorry, I don't have any personal experience. However, I have read a few times that the 5.7 is better for real world use.

I have the 6.4L and like it a lot. It's docile and idles at 600 RPM. When you want power you have plenty to spare. I never drove a 5.7L to compare but I like a lot of power in my vehicles. Source all the outlets that you can and you can get a 6.4L for slightly more than a 5.7L. There are other options available such as the G.M. LS series of engines. They range from 5.3 - 6.2l. You can get an all Aluminum block which is lighter in weight I feel these are better swaps as they are more compact & easier to cool. These swaps are pretty refined and emissions complaint when done correctly. Being in California & here in Colorado that is really important. Either way you will love a V8 in your JK.

I put a 6.4L in my JK about two years ago and absolutely love it. A good friend has a 5.7L in his and he loves his as well. I have driven both and I don't think there is a bad decision to be made here. We have gone out together and I can't say one is better than the other on the trail, but I am sure there are situations where either one can reign supreme. I chose to go with the 6.4L as the cost difference was not that much based on a deal on got on a crate engine. If you enjoy power though, the difference between the 6.4 and the 5.7 is definitely noticeable.
