The 6.4 fits decent I have a couple bolts in the trans bellhousing and the mounts bolted in
No exhaust ,the headers look like they will be a real pain but they always have been even with the old stuff
 
Is there a physical difference between a 6.4 and a5.7?
I’m not sure if there is any differences between the two I know the heads can be switched from a 5.7/6.4 so I dunno

This is a stock 2014 vvt 6.4 from a ram 2500 that has been setup to run on a carb
 
That 6.4 will be alot of fun, I have one in my truck, plenty of power, but horrible gas mileage.
 
Thinking about running it completely stock just to see what kinda ET it will run
Yup going in my dart sport
Will likely add pistons and rods
13.5 to 1
And a cam

The truck intakes are taller. The car intake is lower for hood clearance. The truck intake is suppose to flow better because of this. So I've been told.
 
The opening post made it sound like they would be a more difficult install.
I am not all that familiar with gen3 other than maintenance on my ram.

It is very tight, but they do fit. Not the most glorious job in the world to do, but, there's worse things. They in fact are the ONLY thing that seems to fit. 2010-2011 Jeep Grand Cherokee 5.7 manifolds fit, but, will be waaaay to restrictive on your 6.4.
 
the TTI headers do fit, very tight, do your self a favor and open up the holes in the flanges the holes are extremely tight tolerance and are not forgiving at all. I fought my drivers side for almost three hours before I just pulled it and opened them up. also on the drivers side the #3 tube, start those first then the rest, for some reason TTI like to make that a *****. Just like my traditional small block headers. and last but not least if your proportioning valve is in stock location you may want to move that up towards the master cylinder while the motor is out, the tubs are very close if not touching the proportioning valve.

Correct me if I’m wrong but I believe you are the member that switched from a 408 to
5.7 based 392
If so are you up and going with it yet and
Any regrets??
 
I am the guy that went from a 415 to a 5.7 based 392. I am super close to running. I have to prime the oil system and run a few wires for the alternator, radiator hoses and I am running. I have zero regrets doing this. I can go to any dealership in the united states to get motor parts etc. and I am up and running. the difference between me and 408 swinger is he is running a carb and I am running a throttle body EFI system. 408 swinger has two good threads on this site to read thru, and he is up and running.

and I am doing this to a stock front suspension 74 dart sport with a cope race trans behind it

Have started a thread ?
I’m moving away from the 408 as fast as I can can also.
 
I did but have not updated it. I should go back and update what I can but for the most part it is parallel with 408 swinger. he has the same year dart swinger and I have sport. I will get back into it and update. I did also have one regarding my sons belvedere on Moparts but his has completely stalled out due to cash flow. I am just so excited to just drive this car and put a few thousand miles on it.

However I want to move even closer to the new modern tech, so I more than likely will be selling my life long car(Dart sport) to get into a new 1320. My wife has been very patient with me over the years with my hobby but has finally asked me to sell and upgrade so she can enjoy it with me. small price to pay for a factory 11 second car with air conditioning and spending more time with my wife. Part of me is bummed out, but the other part is excited to get the 1320.

Congrats on nearing completion with your DS. That's a good looking car and with the late model tech, it'll be REALLY nice. I'm in a similar position as you. Building my '69 Cuda originally with a MP 5.7 but haven't been able to resist upsizing as Mopar keeps coming out with better and better. My wife has been very patient and supportive as I've gone from 5.7 to 6.1, to sending the 6.1 to BES Racing (now a 393 stroker that's for sale), now replaced with a HellCrate. This car will be sooo cool if life would stop getting in the way of me finishing it. In the meantime, I've upsized from 5.7 Challenger R/T to 392 Scat Pack Shaker and now a Red Eye. The RE is bad ***, but all I can do with either of my cars (Cuda when done and the RE) is bracket race. The new 1320 is such a nice package and legal for STOCK AND SUPER STOCK! OMG!!! If there is any way you can swing keeping the DS while getting the 1320, you'd have the best of both worlds.

Oh, and as supportive as my wife has been with my Cuda, she would LOVE to see me sell it and just enjoy my Red Eye. I've certainly thought of it, but have always swore I'll finish the car, regardless of what twists and turns life throws at me.

Just want to jump in real quick, not trying to high jack but looking for clarification, 2010-2011 Jeep Grand Cherokee 5.7 manifolds are PROVEN to fit in a 74 Dart Sport? Plugging in a 2014 5.7 to my 74 sport and hav shears plenty say it won’t, and plenty say it will....

Yes, they do. With a couple slight modifications. The 73 Scamp is the same front dimensionally as your Sport. Please refer to my 73 Scamp 5.7 Swap thread and look closely at the pics.73 Scamp 5.7 Swap
 
Yes please. Keep us posted. I have a rat rod pickup builder friend that has been doing LS swaps for years. Because of their popularity, they are pretty much plug and play. I haven't followed Gen 3 Hemi swaps but things should be getting close. Subscribed! Thanks for letting us tag along.
