I'm looking at putting a 6.4 in my 69 dart, it's an srt motor with all the stock wiring harness and ecu. I know I'm going to need headers and an oil pan, I plan to run a th400 with a small block 727 bell housing. Besides a tune and probably a programmer, what else will I need? I'm just getting into this and there's so many different things I'm reading in trying to get a handle on what I need, not what everyone else needs.
 
My initial observation besides the things you have mentioned would be a compatible fuel system.

We recommend the Aeromotive drop in unit opposed to some of the economy offerings.
The aeromotive is fully anodized, and resists corrosion...the economy offerings have brass and zinc fittings....not very compatible with ethanol blended fuels if you ask me.
Aeromotive - AEI - AEI18688 - Phantom Stealth Fuel System

you can even do a rear mount filer/bypass kit to eliminate a canister filter, and you only need a single line running forward.
this allows the pump to keep cool fuel flowing, and prevents heat buildup and cavitation.
PACE Performance - PAC-9926 - Pace Pac EFI Fuel Filter with Regulator Package

cooling system comes to mind also as the radiator in/out are both passenger on a hemi. We sell the be-cool modules.

anything you're specifically wanting besides the above? As you mention this is YOUR build..so I didn't want to throw you a bunch of stuff you're not interested in or needing...
 
Thanks for the info.

At the moment I just want to get the motor in and running, thats all I am concerned with, I will worry about bumping the hp up later.

understood, and you'll need a fuel pump and cooling system regardless of HP. so thats why i started there.
 
Following.
Not there yet but A G3 Hemi in the future for my 69 Barracuda Fastback.
Seems almost every day there is a new offering for the G3 swap. :)
 
Yeah, I am just trying to figure out what the bare bones I need are.

I have an A1000 fuel pump but I think that might be too much?

I have read all kinds of different info, thats why I am wondering what it really takes to get one up and driving.
 
There are easier ways tan a stock harness to do this swap. Cheaper ways too. As far as fuel pump, A1000 is drastic overkill.

Yeah, i figured. No luck moving my big block stuff so this swap isn't looking real promising anyway.
 
why not do fuel injection on your big block? In all honesty if you already have a good running motor that is the route I would take. Gen3 hemi stuff is still unbelievably expensive. You can probably put a nice coil on plug EFI setup on your motor for under 2k.
 
Johnny, A question for you. I've got a Aeromotive 340 stealth pump and 10 micro filter in my fuel system for my 6.4L hemi (1970 Dart). From a previous part of the build I have the corvette style filter regulator ( supplied by Bouchillon) plumbed in the fuel system. Aeromotive tells me I cannot run this filter/regulator because it will burn up the pump. Do you agree with that?

Sorry, I somehow wasn't subscribed to this thread? or missed my name, sorry. We use the corvette regulator/filters. We have found that aftermarkets aren't up to the task. They sometimes wear out, or don't hold pressure where as the GM units, we never...ever... have issues with them. I have Had a recent discussion with Aeromotive about this, and they claim they do see issues related to theses "type" filters...but then the extra part of the conversation where it would be discovered if it's a GM filter, or an autozone filter, doesn't seem to happen.

Seems to boil down to aeromotive has documented some issues with "bypass filters" where I personally have not warrantied one of mine, or had to warranty an aeromotive pump or GM filter in 3 years.

I don't however want to put anyone in a position that may lead to an issue with warranty or replacement at aeromotive. I think a true bypass regulator is probably the "best" option for everyone if you're set on the phantom. Or if you're open to the holley in-tank system, that one is returnless. For what it's worth to anyone making a decision on one vs the other. the -6an EFI aeromotive regulator has the same exact orifice size in its return port internally, as the GM corvette filter. To each his own however, and we can set you up however you want to tackle the project.

nevermind, dont wanna debate why that regulator is not a good piece

No debate required. If you dont like that style, then dont run it. Multiple ways to plumb a fuel system. And we can accommodate any of them.

I'll say this and then I'll leave it alone. As someone who's tuned literally hundreds of gen3 cars over the years, I don't recommend anyone run that regulator. Spend twice as much on a good regulator that will hold 58 psi and in turn you wont have a car that runs like crap that you have to pay someone like me to tune.
