Title: 6.1 Hemi/NAG 1 in 70 Challenger
Post by: soundcontrol on March 04, 2017, 01:08:57 PM
Here is my swap. For my 1970 Challenger convertiible. I got a 6.1 Hemi with a NAG1 from a 2006 Charger. I also got the harness (but I got a new one from Hotwire), computers, shifter, gas pedal from the car. First I was gonna use my 727, but I changed my mind and went with the NAG1. I ordered most of the parts from Bouchillion, harness and programming from Hotwire Auto, gastank and pump from Tanks Inc. Here is a list of the parts I ordered.

• Milodon oil pan
• Milodon oil pickup
• Milodon Dipstick w. tube
• Griffin radiator with 2 fans
• Upper and lower radiator hoses
• TTI engine mounts
• TTI ceramic coated headers fitting Hemi/727/T-bars
• Oil filter adapter
• Oil filter short
• Fittings for AC compressor
• Power steering pump with reservoir
• Cold Air kit
• Serpentine belt
• Air Charge Sensor
• GPA-4 - High Flow Fuel Pump Module
• Fuel Tank Sending Unit
• 24" Strap Liner
• Dodge Challenger Fuel Injection Gas Tank
• Challenger Gas Tank Straps
• Adjustable Fuel Pressure Regulator with Gauge
• NAG1 tone ring and 2 speed sensors
• Harness Hotwire Auto

Has anyone put a total cost on what the parts cost to make a swap like this?

The swap progess is slow since I got the car in 2k epoxy now and adding body reinforcements and will change the trunk floor and fix some bad patches. I got the Milodon pan on the engine though, I got the wrong oil pickup, so I cut it and reclocked it so it fitted. Next step is cleaning the block and paint it.  First pict is the wrong fit of the oil pickup (got one that fits a 2009 and up 5.7). Next pict is the fix.

For me, (the parts I listed so far):
Bouchillion:  $3952
Tanks Inc: $680
Hotwire Auto: $2409

Correction: The Bouchillion order also has the stuff to run a 727 tranny in the price, flexplate, kickdown wire etc. I did not list those since I sold them, so take about 200 off that price.

All including shipping (US shipping, to a friend in WA who ships to me in container)

There will be some more stuff later, I'm sure. Forgot to buy sparkplugs, need AC hoses etc.

6.1's, 4-7000 depending on the milage, tranny etc. There is a few on e-bay. You can find a 5.7 cheaper.
I just bought a 5.7 for $2700 with harness and computer. For my next car. Thats a good deal here in Sweden.
We usually have 30-40% higher prices than you.

where did you get your oil filter adapter from?  Was it a 45 degree angle one?

The filter with/without an adapter will not fit with a k-member.  If your running a tubular type, then it will fit.  @MoparDave (https://forum.e-bodies.org/mlist/mopardave_10) can get you an adapter.

Best route in not an adapter but use a block off plate & route hoses from the side of the block out to a remote filter set up

Thanks, I'll probably run the factory K member at first, then as funds open up, switch to the alterkation setup.

Yes, a 45 degree adapter, it will fit the stock K-member with a slight mod. and a short filter.
I got it from Bouchillion.

We did the same mod believing the same mis information , we had to trim the entire lip off the adapter , the K frame still hit the filter & the filter was not removable without undoing the engine mount & lifting the engine .
Trust me this will not work , use a block off plate , if you have not cut the adapter don't just return it .

Mauls ... Please Drive a car with the Alterkation mod before converting to it

Hmm, I just went with the information I read in the Hot Rod Magazine article when I ordered all my swap stuff, but I have seen many others do the same thing, using a shorter filter. Can't return stuff since I'm in Sweden, have to try it out anyways, if it don't fit I guess I'll order the other kit then.

I never saw a reason to go that route. New arms, coilovers, and a rack doesn't automatically mean "better", to me. It's flashy, but there is little performance justification on their site.

the front rack steering has never been sorted out for a Mopar
I believe AlterK uses Pinto parts

Oh be nice... It's Mustang II...... But wait... The Pinto came out four years before the Mustang II & has the same suspension... So is it a Pinto? Nah, Mustang II sounds cooler..... :haha: :haha:

I've worked on/driven two... they both had the same issues & it clearly pointed to geometry problems....  They were never great as Pinto's & Mustang II's but widen the track & increase the wheel base and the numbers are all wrong....

Nope, far away from up and running, I cut the quarters off, then my project came to a stand still because of work. It moves very slow now, but its OK, I enjoy it anyways. Good thing with the oil filter adapter! Maybe it has do do with what kind of engine mount are used?
Great if you post more info on your swap!

Your car looks great! What year? I also bought a -73 project (rust bucket) and a 5.7 Hemi / a833, just in case I get more time on my hands,  :haha:

On my 392 Hemi the oil filter adapter and any oil filter would not fit with a k-member.  We cut the "tongue" off the oil adapter and installed an adjustable remote adapter to a filter mounted on the k-member.  Maybe its a difference in the 6.4 vs. 6.1 or year change.

I do not beleive this is an issue with a tubular k-member (QA1, Magnumforce, etc) from pics and research I have done, but I have not done a tubular k-member install.  We are planning to do this on @CudaKat (https://forum.e-bodies.org/mlist/cudakat_79)'s '73 Cuda with a 6.1 Hemi but the car is currently at the bodyshop so it will be awhile.  There is a FB page on Gen 3 Hemi swaps that has some good information and pics and helpful guys.

Very slow!  :(  Have not done much of anything since late July now, got a TV show and been working 80-90 Hr weeks for 3 months. I just finished that though, moving on to some movies now, the deadlines are not so tight on the movies so I'm planning to get some more work done on the car during the winter. I compensate by ordering tools online while I work :)
Thanks for asking!

Yes, I have a brand new shaft in a box that I'm gonna send off and add a slipjoint. Waiting with that until I have the engine/tranny in the car so I can take some measurements.
