Started the HEMI swap in my 1968 Charger

[TTSaleen]

Yep.  Actually started the swap in the car by pulling the original 318 engine out.
Here's a couple pics along with a video (I love to document stuff for future reference).

Started a little more progress.
Dropped the 5.7 HEMI in the car last night.
Hooked up the NAG1 transmission.
Tried to complete the transmission crossmember (Hooker brand), but ran into a problem.
The factory tunnel is too small and it hits.  I found that Hooker makes a replacement part that goes in there so I had to order it (next week before it ships).

A few things.
The alternator fits.
The A/C compressor does not fit.  It hits both the motor mount bolt and some of the K-frame.  So I need to get a shorter motor mount bolt and notch the K-frame slightly around the motor mount support.
The oil filter relocation kit came with 45 degree fittings for the block, but you cannot install both as they hit each other.  I ordered a straight #10AN to 3/8 NPT pipe fitting and installed on the bottom and it should now work fine.  You need the 45 at the top to clear the alternator.

Need to hammer on the tunnel a little around the shifter area and massage a few items on the trans where it might hit the body once the trans is up fully in position.

Wow changes! 

[TTSaleen]

What ya doing with the old stuff? 

Sorry I didn't respond to this before.
While this is the original engine and transmission out of the car, I really don't have a place to store it indefinitely until one day when someone buys the car (when I'm long gone).
After all the work I'm going to do on the swap over and modernizing of the drivetrain, I am never going back to the 318/904 combo.
So most likely I'll sell it.

If you are interested, let me know.

Also here's a recent video of the HEMI going into the Charger and I talk about some of the issues.

I just read the statement about the tunnel being too small and a different crossmember needing to be used and hammering the tunnel.  You seem to know a lot more than me, but I'll chime in anyway. 

I suggest setting it up now with the proper driveline angles and if that means cutting and modifying the tunnel rather than a different cross member and hammering, I would opt for that. 

Thanks for posting. 

[TTSaleen]

Somewhat of an update.
Been waiting on Hooker to send me the crossmember support bracket.
The painted one I purchased is not shipping till end of the month but the non-painted one is in stock.
After going back and forth, they cancelled my 1st order and had me reorder the non-painted one.
It arrived in 2 days.  

The instructions say you have to modify the floor with a hammer and body shop tool to clear the brace.  Well after a bit of hammering, there was no way this was going to fit.
So I chose to slice an opening in the floor and peel back the metal to get the brace to fit properly.
I plan to hammer the floor back as flush as possible and then have it welded around the brace for strength.  Then apply seam-sealer and paint.

Also it is a good idea to drill the 4 holes between the upper crossmember brace and the lower out a little larger (1/2") to allow easier bolt access.

Finally the NAG1 rear mount holes did not line up with the crossmember as advertised.
I attribute that to the TTI engine mounts I used and not the Hooker mounts (which they state you must use).
I assume the Hooker mounts move the engine forward about 1 to 2 inch and would make the holes line up in the NAG1 mount.
I simply redrilled the holes and had to modify the structural support by cutting the metal back and grinding the plate flat in that area for the rubber mount to fit flush.

But the NAG1 transmission is now in place.

Some updated progress pics.
Working on a video, but I know unless you are doing this swap some of this stuff is not exciting.   

[TTSaleen]

2 months later, still waiting on Hotwireauto to build my wiring harness...........
in the interim, I've upgraded the entire fuel system with the following -
Aeromotive Stealth fuel tank with 340lph pump
8AN feed line, 6AN return line
PTFE lines from Fragola 6000 series with their fittings

Also started the battery relocation kit (putting battery in trunk since it no longer fits comfortably in the engine bay).
Got the kit from Summit Racing.  I like the look of the black plastic box instead of the aluminum one.  Sadly my current battery is too big, so I have to source a smaller size.

Here's a few pics.

Great job !!!!! lookin AWESOME  

Thanks guys.

Picked up my new custom driveshaft today.
I talk about it in an upcoming video on my YouTube page soon.  Working on editing it now.
I figured I'll throw in the fuel system upgrade, battery relocation, and driveshaft all in one video to make it interesting.
It's hard to figure out what the audience finds interesting (for those that aren't building a car or doing this particular swap).

Hi,

Following your build with great interest. 

Question about the cooling system: what radiator and fans are you using? Does the radiator opening need to be cut? How about mounting the radiator?

[TTSaleen]

Hi,
Following your build with great interest. 
Question about the cooling system: what radiator and fans are you using? Does the radiator opening need to be cut? How about mounting the radiator?

Hello.  Happy to answer.  The radiator and fan combo came right out of the 2006 Dodge Charger Daytona donor car.
The 68 Charger opening is factory (no cutting), however I did have to fabricate some mounting brackets and drill some new holes to mount the radiator.
I also used bolts and some spacers to ensure the radiator and AC condenser were mounted properly and not make contact that might cause a leak later on.
I also incorporated the factory rubber isolators top and bottom of the radiator to allow it to move around some and minimize vibration as well. 
Those radiators are plastic and can break/crack (known issue).
For the cooling fans, I am running the Dakota Digital 2800BT controller.
Thanks!

First test drive last night.
Car runs, but I have a problem with the transmission not shifting in AUTO mode.
I assume this is a problem getting a signal from the speed sensors and that tone ring mod.

So have some bugs to work out, but the car made it a quick 2 mile round trip to the store for gas and back.
No overheating (fans and thermostat work great).
Charges battery great (over 14 volts consistently).
New steering box and suspension mods feel great.

Sweet!

[TTSaleen]

Getting to the final steps to complete my Gen III Hemi and NAG1 transmission swap in my 1968 Charger.
Unfortunately I haven't quite sorted out the speed signals to the NAG1 and it is causing Limp Mode and not shifting consistently.
Hope to get this sorted soon.
Otherwise the car starts, runs, and drives really good.

Started modding the console to try to make it look factory with the 2006 shifter.
Last picture is a test-fit.  Still working/massaging it to fit better.
That chrome trim surround of the shifter came right out of the 2006 Daytona donor car.

Look at that.
Just received my Russell Drake NAG1 solution tonight (1 day early I might add).
Now to get this installed!

[b5blue]

So that will fix the "Limp mode"? 

[TTSaleen]

So that will fix the "Limp mode"? 

That's the plan.  This does away with the ABS computer and sensors entirely.
I'm working on it now, just have to get some new bolts for my driveshaft to mount the tone ring properly.
Already removed the other tone ring, ABS sensors, and abs computer last night.

Good luck!!

Nice Charger! Sorry if I missed it, are you using a factory PCM? I've seen where people hack out the cross member and just leave it at that. Did the car seem weaker missing part of the cross member? I like how you reinforced it after clearancing 

[TTSaleen]

Yes factory Engine computer, Front control module, and transmission control module plus this new Russell Drake NAG1 adapter controller.
You could just hack the top  of the floor and crossmember, but you lose critical strength in that area that the torsion bars use for lateral strength.  Holley Blackheart series has the piece I used that adds the strength back in and gives more clearance at the same time around the transmission output shaft and driveshaft flange.
However on our cars, it was still not enough to run the ABS style tone ring.
Ryan

[metallicareload99]

Did the PCM need to be reflashed and all that or plug in play? Excellent work by the way!

[TTSaleen]

Yes my original modules (ECM, FCM, TCM, etc) had to be sent to Chris at HWA to be programmed with his harness he built.
In my ECM tune, he diabled the EGR, Cats, and MDS features.
However his tune nor harness provided can control the cooling fans (you must purchase a separate fan controller), nor does he do/offer any performance tuning (I requested 93 octane tune and was denied).
He uses HP Tuners software and keeps it unlocked so you can tune it yourself or seek out other tuners to write you a custom file (which I am in the process of doing).

[TTSaleen]

Here's a few progress pics from last night -

1.  Using a 30mm socket, remove the rear output flange and slide it off output shaft.
2.  Slide on new tone ring with indentions facing rear of car.
3.  Slide factory output flange back on and reinstall 30mm nut and tighten.
4.  Next I installed my 3 to 4 bolt 1350 u-joint adapter and bolted it up.
5.  Then it was time to remove the upper NAG1 mount to crossmember bolt to install the sensor mount.
6.. Put bolt thru mount first and then install sensor - ensure sensor and jam nut are flush to each other.
7.  It's tight so an open-end wrench is necessary to tighten the mount and bolt back up.
8.  Ensure all connections are tight and run wire so not to interfere with any moving parts.

Tonight I'll finish up the wiring to the plug and it will be ready to test.

I gotta say there is a lotta crap to sort out for this swap! My hat is off to your efforts!

Green on Green ?

It's Monotone Racing Green Metallic with white/green interior.
Basically the door panels, seats, headliner are white and the carpet, dash, rear package tray are green.
The original owner (lady) I bought it from had special ordered/requested it this way as she liked those colors.
It's not the color I would have picked, but its definitely grown on me since I bought it.

Now it's getting warmer here and I need to fix the AC cooling system.
I have the G3 Hemi AC compressor that came out of the 2006 Charger on the engine now. I also have the condensor. However I need to make up new lines, get a new dryer, and figure out what else I need to convert to R134.

Have any of you made your own AC lines? Do you have a recommendation on the lines, fittings, dryer, etc that I would need to buy to make this myself?
I can buy freon and have access to the professional gauges and a vacuum pump to get this thing filled, but I need a way to get started on making the lines and any other parts.

Thanks for any advice!

Ryan I used Classic Auto Air's system. Drop the box and it replaces everything with modern non vacuum controllers. Check their web site, I like mine.

Nice work! My '69 needs some gear bad so your videos are really helpful for planning the job.

You should bring the car up to Cars & Coffee in Morrisville sometime, 1st Sat of the month and pretty good turnout, I'm usually there with mine and we need all the muscle cars we can get
