I haven't seen any threads about this question. Has anyone installed a 6.4l in there 06-10 SRT. I've been told that its now possible.

No one that I know of has done it.... Not sure if the wiring harness would be the same for the new 6.4 liter in a 2006 to 2010 jeep...

They have a aftermarket wiring harness and computer. And they claim the MDS wil work also. I only ask because the 6.4l is cheaper buying it crate. But I believe after buying the harness and computer the price is almost egual to having it stroked to a 426.

You can buy a 392 short/long block from any of the vendors on here. Why give yourself a headache with an untunable engine.

Last summer I was speaking with a racing vendor and they were playing with that ideal. What was holding them back were the encryption codes. Fast forward to today ...they say that problem has been solved.

Yup exactly what I was thinking or even upgrading a 6.1 to a 426..... Plus I thought they were saying the crank on a new 6.4 was not forged and would not be good for boost as to why they are coming out with a 6.2 liter motor....

I'd get a 5.7 or 6.1 based 392 that has been battle tested multiple times and be fine, plus you'll have an engine built to your needs, fully forged, boostable, and highly tune-able.

^^^^ What Eric said, why get a stock crate setup when you can turn your existing stock 6.1 into a handful of different sizes built around your needs and goals. You'll be able to push big numbers with a motor built the way you want with whatever FI power combos etc rather than being stuck with a stock 6.4 that makes 50 more hp than the stock 6.1 does.

Towards the end arond the 3:54 mark, he says its a forged crank.

Do you mean put the new 6.4L in? What would be the point of that? The 6.1 can be bored out to a 6.4, 7.0, 7.2.....and has tons of aftermarket parts available. Why would you want to swap to a newer, weaker, unproven engine, that has very limited tuning, and very few performance parts available? It hasn't even been proven that the new 6.4 can safely handle boost.

^^^This. You will spend a very comparable amount of money between the two options, but the stroked 5.7/6.1 motor option will allow you to produce much greater power.

It can be done we have done the swap on a few 09+ Challengers and Chargers already
and you can tune them.

[RonnieMac69]

[Black jeep Srt8]

I did a 6.4 swap it is possible but it little things that got to get done like oil pick up tube has to be heated up and bent oil pan gasket got to get cut out and more
