This one feels meant to be! Found a set of those exact wheels/tires on FB marketplace. Mounted but never driven. 225/45/R17 with 0” BS. Seller even delivered to my shop.

Couple more pics from today. Wilwood brake kit should be here next week, along with my transmission components and clutch kit. Only have the rest of this month to work on it but then I’m busy from September through about Thanksgiving! Very happy with the recent progress though. I’ll be stabbing the engine in sometime soon to get an initial mock-up with oil pan and steering components. Then gotta tear it all out again to finish weld my engine mounts and paint everything.
Thanks for all the help so far.

Any progress?

FYI, looks like the 6.4 intake does add power when locked in the long runner mode. Found people talking about how the intake helped even before they got the SRV switch working. Earlier in the thread, I speculated that the 6.4 wouldn't be any better than the 5.7 intake if the SRV wasn't working but it appears I am wrong.

No sir I’m typically swamped with work and hunts from Sept 1 through about thanksgiving. A guys gotta have multiple hobbies you know? :)

Plan is to haul the car to my buddies shop end of November where we’ll do the trans tunnel swap, relocate spring perches and possibly do a mini tub.

I did find a set of tires I’m planning on running on the rear. Plan to run the 305/45/R17 Nitto NT555RII. I may end up buying a second set of rear wheels and just swap the Nittos on for more traction as I’m seeing them only lasting 5-8k miles on the newer challenger. I can’t find any other tire brands or models in that size. They advertise them fitting a 9.5” wide wheel.

Thats good to know on the SVR runner mode! I’m still unsure on going Holley or Megasquirt but leaning MS for the system and it should be able to control the SVR module.

I’ve got my wilwoods and clutch kit as well waiting for install. Once it’s mocked up I’ll be inspecting the Z bar clutch linkage to see about modification and will make the call on a hydraulic TOB or not.

Lots of plans for this winter. I’ve got the goal of getting car on the road next summer but we’ll see.

You sound exactly like one of my best friends. He works on his car between boating trips, and then drops everything to hunt. Then he jumps back on the car during the winter. He has a '67 Dart post car with a 400/4speed.

Do your homework on the Holley and MS. I run an MS3X on an LA engine. Their new AMP EFI controllers seem like much better packaging than previous products. The capability is certainly available on the MS, but it does have a big learning curve if you haven't messed with tuner studio. Holley's software seems more intuitive and their digital displays are really nice. There are displays available that work with MS via CAN bus, but I don't know if they are plug and play. From a price prospective, I think the terminator X is more in line with MS products. When they only had the dominator product, it made sense to go with MS.

My only hang up with the Holley is the Terminator X/Max doesn’t have traction control like the HP or Dominator does and that’s a must have for me. Okay, not a must have but it’s a feature I want for the street. I’m looking into a little more of how to get the dominator to work, have found some google results of gen3 dominator harnesses but no purchasing options so I’ve got an email into Holley Tech support.

The digital dashes are legit! Wouldn’t break my heart at all to run one. I’m close to pulling the trigger on one of these setups just need to finish up my research a bit. Going to YouTube some tuning videos for both and see if one makes more sense to me or not.

Mike @ HCA

ALSO…. Probably going to order custom plates here soon. Looking at the following:

You are correct. I put wheel speed sensors on my car and the MS3 handles the traction control and its a neat feature to have. I put mine on a switch so I can turn it off. The terminator also has limited I/O so if you want to monitor lots of data, you will run out quickly. They do make a CAN I/O extender as does MS.

And no internal datalog for the Terminator X as well.
I’m fairly certain I’ll be running the MS3pro EVO with the amp connections/box. I really dont like how they don’t include the WB O2 sensors/controller but whatever. Not too worried about tuner studio, there’s always a learning curve and I do have a good tuning resource to analyze my logs if needed.

Agree 100%. I wish MS would get on the bandwagon with the screens and the built in O2!

There are some CAN bus displays out there that work with MS, but I honestly haven't looked into them much.

If I were to do it again, I'd use the ProEVO as well. It's much smaller than what I have and I like the connectors better than the old school DB connectors I have on mine.

From my research over the weekend this dash is an option for me. I have the ability to machine a custom dash I'm just not sure that this display will fit or not. It would be easier for sure to just run aftermarket gauges in a custom dash with the circular cutouts but a digital option would be legit. Not a lot of room height wise on the A bodies for a decent screen size!

Well took a little time today and dropped the engine in and bolted up the headers. Everything went fairly smooth. I need to take intake off and put the SVR module back on to see if it fits. Headers fit like a dream.
However the factory truck oil pan and pickup is a no go. The cross brace for the steering interferes with the pan. Could shift engine rearward slightly but I don’t think it’s enough before contacting firewall and definitely couldn’t run the SVR module in that case.

Wow! Looks great in there, I like it.

Any chance you could grab a measurement between the radiator and accessory drive for me? The Holley motor mounts move the motor forward about 1.75" and I can save about 1/2" by running the '09-10 accessory setup but not sure I need to. Much rather run the '11+ as it has the chance of better parts supply. Just curious how much room I might have.

However the factory truck oil pan and pickup is a no go. The cross brace for the steering interferes with the pan.

I've been waiting for the Holley pan to be back in stock, but pulled the trigger on it today just in case they keep selling out before they get them restocked. Hopefully I get it before next winter when I hope to start my swap. :)

I’ll get that measurement for ya!
I bought my Holley pan on eBay and got a shipping notification already today!
Here’s a picture with the item number circled for ya.

Thanks!

I put my order in through Holley this morning, and called to talk to someone about cancelling my order and the department is closed. I guess I will give it a shot in the morning and see how it goes.

I wonder if that is part of the reason the date keeps slipping. Resellers buy them up in bulk before the next shipment drops and when it does they are all spoken for so the date rolls out to another later date.

Got my order in. Appreciate the heads up on where you got one.

Holley rep said they had 74 on back order and that it looked like a shipping issue. Shipping through Holley was free, but for an extra $10 buying the one on eBay means I shouldn't have to worry about getting one.

That’s awesome glad you snagged one! I’d had one on order for probably 4-5 months through Holley so was a little upset when I see them in stock at other vendors and dealers!

Next steps for me are to gets trans in position and check trans mount location, verify steering column fitment, oil pan fitment, and SVR fitment. Then I’ll pull everything and finish weld/paint k member assembly, cerakote headers and plan a weekend to do the trans tunnel modification.

Hoping to get it on the road next summer, with plans to finish out interior next winter.

4-5 months? Ouch. Makes me feel even better about jumping on one now. I looked around yesterday before I ordered from Holley but didn't trust that they actually had one in stock.

When I ordered my headers, it was right after they went on backorder with Holley. At the same time, they jump $220 in price. So I called and searched everywhere I could and found a guy on eBay that said he had one in stock at the lower price so I pulled the trigger. Then he couldn't find them in the warehouse and I waited 3-4 months for them to be back in stock with Holley. Guy was true to his word and sent me a set right away as soon as they were available.

My plan has always been to wait until the 2023/24 winter and do the swap then. But my wife had a good point when I was talking to her about this last night. She pointed out that while my goal is to drive the car during the summer and work on it during the winter, if I have the parts and can't wait then I can start early. But not having the parts on hand means I don't have the option.

Plans always change! If you got some parts and some free time there's no point in waiting to at least tackle specific projects. The little things will more than double expected swap time in my opinion, and every project you complete will yield another something that will need to be changed or modified which gives you the time to order components. I'd been told that the factory pan may work with this K member/steering setup. In 2 hours of dropping engine into place I realized that wasn't the case. And now I'm not up against a deadline so it's not a big deal :)
My original plan was to take my time and enjoy the process as much as the product and do it all right, the first time. But I don't want that added pressure of a hard deadline, so I think it's reasonable to finish up the drivetrain this winter, rewire the entire car and install the megasquirt. If I get a few open header cruises around town next summer then perfect haha

Ugh. Went back and reviewed your thread and discovered I have twice now covered the same stuff. In my defense it was a month and a half ago, but still. :)

Completely agree. I've already spent time mocking up the motor and motor mounts to try and figure out if I can run an OEM TR6060. Figured out the starter won't work but due to the work I ended up talking to a guy on FB doing the same thing and he figured out how to make it work.

Did you get your pan?

I got mine and noticed that the oil return ports aren't drilled and tapped. I don't expect to ever use them, but makes me wonder what is up.

Just pointing it out in case you hadn't noticed and did have plans for them.

very nice, sorry I am so late to the party (build). In my defense, it is tuff keeping up with everyone, especially since your real names are different than your screen names.

I saw a question regarding the OEM A/C compressor fitting with the HDK, Yes it does, and it is one of the reasons the Gen III mounts look the wat they do. Also Jeep manifolds fit without modifying the engine mounts.

Thanks for posting,
Denny

I did receive my pan but haven’t gotten to look at it too much yet! Good to know.
I just got back from last trip of the year and my custom plates were waiting for me. :)
Be a week or so before i get caught up enough to start working on the car again. But I’m anxious to get started!
