The Hemi 6 Controller works excellent!! It basically uses the same software as the Digital 7 programmable via laptop.

I've run best of 11.05 @ 122mph at 3400lbs. Motor was a stock shortblock, ported heads, PWR cam. I hurt the stock short & blew it up at Monster Mopar, so I have a new motor in the works.

Congrats and sorry to hear you hurt the short block

What were you reving to and which engine 5.7 or 6.1?

6.1 motor...had about 10,000 miles on it when purchased. I left the short alone, ported the heads, PWR 224/228 cam, DP intake, carb. Made peak power, 557HP at 6400, shifted at 6800-7000. Motor melted down at about 6200 rpm, after shift to 3rd gear.

Forge the short, maybe a little more compression and cam and you will easily be running 10's.

Nice work
Almost in the ten's with a stock 6.1 Hemi.
Try that with a 340 or 360.
I wonder if you would of got the tens with the factory intake and Computer.
You said your running a 6.4 block for your next build. Is this the new factory SRT8 block with the bigger camshaft? Thanks for posting

I do know what would've got me into the 10's with my previous motor.

My existing headers were too big for 370" which cost me torque which in turn affected my converter stall. Car was a pooch out of the hole as the converter was hitting at 4500, when it should've been hitting at 5300-5400. 1.60 60's with a ladder bar & no tire spin. I dyno'd my motor with 1 3/4" dyno headers. Early on before the dyno, I built a set of 2" primary headers & they were way too big for the motor. I'll bet it cost me easily 30-40 ft. lbs. Live n Learn!! Bigger is no always better!

Had the torque not been down, it would've been there in the 10's no doubt.

Yes, I have the new SRT8 6.4 block.

But calculate the cost... If you buy a 6.1 swap including the PCM, wire it yourself (not really that complicated, just time consuming) or purchase one of the $750 kits you can buy a used Predator tuning device for $200 and either attempt to tune it yourself or pay me $375. Now you have a grand total of $1500 (or $600 if you wire it yourself) invested in a killer, factory designed system.

I don’t post here too much anymore as my interest have changed. But occasionally something is brought to my attention. That said, I have 2 cars that I converted over to factory EFI 6.1L's. Ones a 4spd the other an auto. Your comment above caught my interest. If I am reading right, you are saying someone can take a LX series PCM(I used 2004DR PCM's)and use it for the conversion? If so, what are you doing about the SKIM(if activated)or the other inputs that PCM is requesting? Also,what year is most compatible? I have(3)2007 LX 6.1L PCM's in my possession.

Also, what is this $750.00 kit you are referring to? Can you be more specific?

---

First off, being selfish, how much do you want for the LX pcms?

Second, my only experience with the swaps has been with 5.7 truck engines (a local truck salvage company calls me when they get these in).

They have all been 04/05 model years. And there have not been any SKIM/VATS issues to deal with.

I called to verify my cost on harnesses and waiting on a callback. However, there seems to be quite a few out there but the retail is $950

I will try to get the specifics if other year units will work and if so what is required (from the same company I buy my harnesses from).

I am also updating my previous post (if I can) recommending that pre-2009 PCM's should be used.
From a CMR tuning perspective the pre-2009 has active VE tables but if the SKIM or other CAN bus issues are involved then the only option I can validate may be the 2005 5.7 truck PCM.

Good call out and I apologize for being misleading if in fact the other model year PCM's will not work.

540Challenger - Is there a specific reason why you are considering a 6.4 block? I have not had any of the 6.4's in the shop but was wondering the benefits over a 5.7 which seem relatively easy to locate for cheap? Nothing against the 6.4. From what I've read it's the same bore as the 6.1 with the crank having a longer stroke. I also read that there are oiling passage mods but I'm not sure if they are for the MDS or overall improved oiling.

I just wanted to know if there are any specific advantages I am not aware of.

Thanks in advance!

Question on the building of these engines,,,what kind of results are people seeing, re-using the original gaskets? I am referring to the water pump, valve cover, spark plug tube to valve cover, timing cover, etc...the o-ring style gaskets. Rumor has it, that they are designed to be re-used. I thought if in good shape, they would probably be OK,with possibly some sealer. What have others found out?? THX

My reason.

1. starting at 470/470 factory should be more then enough to push my challenger into the 11's with a stock engine.

2. cost. IF and that is a big IF the 6.4 is priced at around the same price as the 6.1. 7500.00 from mopar complete with wiring harness and all the senors. IT would be a killer deal.

3. A huge cost with the 3rd gen Hemi's is the core charge most engine builders have running as high 1500-2000. Which i can understand giving the block head wiring and senors cost.

4. With a cam swap, headers and a tune i should have well over 525 ponies on tap.

Granted this all depends on the price of the 6.4L IF it is around the 6.1L pricing.

I'm missing something. When did Chrysler or any other compagny start offering cams for the VVT engines.

How do you manage to tune the production 6.4 engine with the production computer?
Don't take this the wrong way, I hope that someone somewhere has manage to crack the roaming encryption codes that Chrysler is now using. I heard that they are almost impossible to crack

Keep us informed.

I think there is one compnay making cams for the VCT motors I thought remember the name it was on the LX forums but You can always send out the factory came to be reground.

As of now you can't tune the motors but that will changes heck it the same thing was said about the 3rd Gen Hemi when they first came out.

I plan on useing an older PCM to so you can tune it.

The VCT is easy to get around b/c there is 2 companies out there that make a part that locks the VCT in place so you can use an older computer. Modern muscle and Comp Cams both have one.
