I member on here sent me some picture of how he did this when I was having fitment issues.

There are 2 wires that need to go back to ecm from the brake switch .

Good job! Do you have some better pics of this? Is the engine still in stock location relative to the trans?

Thanks again guys. It’s in for mock up and everything is lined up. Modding the isolators now.

Now that looks right since I swapped them. :thumbsup:

Thank you. They give you a instruction sheet and looked like I had what they showed. Will change side to side and retry. Thank you again!!

What am I doing wrong? Pass side seems like it only goes on 1 way. I was just mocking up so no isolators installed. Drivers side seems like it will line up.

For what it’s worth, I can’t see mph on HP tuners either. 04 Durango harness (made stand alone by me) 545 rfe in a 91 D150. Tired tapping my trans output sensor wires to my Speedo ( electronic) and it worked but bounced 20-30 mph.

E and B bodies have been out

1973-1976 A-Body Gen III Hemi Swap System - Holley

Sounds good

Yes, but there are some settings to turn off on the MSD. If you decide to do this I can send you a timing curve and show you what to turn off

I had run it and a modman intake, 650 vs carb. The combo ran very well but the intake design wasn't the best. Switched back to EFi and picked up 3 mph in the 1/4. I made a timing curve for the msd that worked well. I would recommend the OCP intake if your staying carb.

Which megasquirt are you using? Goldbox?

Just keep at it! The payoff will be big once your doing burnouts and you can say that you did it. Nothing wrong with buying a wiring harness either.

Let me know if you need any help. I did my own harness and still have the alldata info. Also have info on the bellcrank and wiring for it which is different than the pedal.

Looks like I’m making about 306 to the wheels. Engine is rated at 345 crank.

Back to the track! Just look at this junk surrounded by Hellcats, Redeyes, mustangs and some imports. Were faster with some minor tweaking and some cooler air. That’s it for this year and maybe for good on this project. So far it has exceeded my expectations and I have to keep reminding myself...

Did some work on the trash truck this week. New heater core, evaporator, condenser. Found this air inlet tube on a 4.7 truck at the JY. Cost me a whole $2.98. Was able to get it to work by making a bracket and I had a filter already. I’ve been monitoring the IATs and they are ambient even...

Fuel system consist of a 340 lph pump in stock fuel hat. I added a regulator and a -6 return

Sound German automotive has standalone controllers for nag1, 8hp and 545rfe.

DIY Hemi.com has stand alone harness diaphragms you can download.

You may want to look into the EFI source goldbox. They require the use of LS/cable throttle bodies.

Holley will probably send for GM throttle body. The terminator MAX with for DBW.

4400 with me and a 3/4 tank of fuel

Trash truck went back to the track with EFI. 100% stock truck computer with no tune. I Datalogged with HP tuners. In a nutshell the factory EFI intake is superior over the carbed modman. We knew this!!!! We are faster now! Made less MPH in the 1/4mile then when it was carbed but I had adjusted...

Get that converter sorted and she will be an animal with the 2 step!

Update: for those asking about the wiring harness. It’s all loomed and I’m happy with the outcome. I’m glad i made the switch back to EFI. Sets me up for my next round of mods. I know everyone loves the schedule 40 PVC air filter ducting. Aluminum one is being made next week.

Update. For guys using the 727/904 trans behind there swaps. There are several ways to control the kickdown/TV cable. I used a bellcrank assembly from a 03-04 hemi dodge truck and use the DIY Hemi website recommendations on how to modify it. Or you can purchase one from Bouchellion performance...
