2011 5.7 swap into Late B-Body

[m79ded]

Hi

Just picked up a 2011 5.7 gen 4 and would like to install it into a 78 dodge magnum which is a big block car. I got the hemi without any harness or intake. I would like the easiest way to go with this so I was thinking a carb and 727 T/F.
It does have the solenoids from VVT on the top as well. Do I have to remove them and block it off?
MSD has an ignition system (6013) for the conversion would that work on the gen4?
I realize the tranny would have to be switched to a small block, but do I have to change K-member to a small block one as well? It has the later model type with spool mounts.
Since I wasn't given any wiring harness I am not sure of what I would need since I am going with a carb. I was looking for an intake but choices are not too plentiful. I looked up edelbrock but saw only dual quad not single. Mopar perf has a single plane, as well but way more $$. I will probably use the stock exhaust manifolds if they fit

Any help on this would be greatly appreciated.

Thanks

I'm not familiar with the specifics of your body style so it's hard to say what you need to mount the engine. First I would call tti and see if they offer anything. Another option is the mounting kit that speedway motors or others that is a generic mounting kit requiring welding and fabrication skills.

Any small block trans will work. 904, 727, 518 etc. you will need the correct flex plate (ati makes one) and your driveshaft may be affected.

Carbing the Eagle VVT is complicated. The cam phaser has to be locked out. Comp cams makes a lock out kit. A 6.1 style intake must be used since the Eagles intake ports are shaped the same as the 6.1. There are several available for carb conversion. Muscle motors has a drag pack style intake, Indy makes the modman, xv has one that's basically the same as the Mopar Performance low rise single plane.
Next is the ignition system. I am not aware of any msd system able to work with the Eagle due to the different tone ring. I know the fast xmi box will work.
Jeep Grand Cherokee exhaust manifolds from an 09- present would be your best bet.
If you use the stock cam, you can leave the 4 mds solonoids in place as well as the mds lifters.
You will need a radiator with inlet and outlet both on passenger side.

Myself after much thought, I'm keeping my 5.7Eagle EFI with a kit from Modern Muscle performance. This enables me to use the VVT and variable runner intake. Much less hassle on my project, in my situation.

Thanks very much for the info. I guess it's alot more complicated than I thought. My bodystyle is very similar to a cordoba, but like i said a big block car whick the spool style k-member is slightly different. I will make calls to the folks that you suggested and take it from there.
I am now wondering if I should look for an FI system and ditch the carb

sounds like fun, but mds and vvt are not the same thing.

Thanks for the info. After doing some research I tend to agree with your last thought (EFI kit) looks like less hassle.
The other alternative is to look at a edelbrock or a holley efi kit. I will do some more research and keep you posted

Lxmodguy can set you up with a stock based system and do your tuning.

I don't know of any aftermarket ECM that will run VVT. The mega squirt 3 is rumored to be capable but is not proven as far as I know.

We have delvelope a true plug and play system that works with the 5.7L VVT as well as the New 6.4 VVT

I am sad to say at this time and after careful consideration I decided not to go ahead with the 5.7 Hemi build due to costs. I was shocked at the prices the aftermarket is asking for essentials that are needed for such a build like engine mounts, intake manifold, wiring harness, computer…etc.
For example to get 4 barrel or a fuel injection intake from Mopar Performance or XV is about $900. The only other reasonably priced items are 2X4 by Edelbrock; even they do not have plans for a single 4 barrel
Computer and wiring harness is about $2500
Mounts about $300
Oil pan and oil filter adapter about $350
Headers about $800
Cam-Lifters and springs about $1000
I realize things are custom but a little reasonable on the price at the same time would be great.
That is about $6000 without everything; I still need starter, flex plate, and assorted pulley’s-brackets and anything else I didn't think of.
At this rate I can go ahead and refresh my 440 at a fraction of that and still make more HP and tremendously more torque which would push around the heavy B-Body around very well.
Heck I can even go with a 505 ci stroker that would do so much better that Hemi for much less.
The huge difference with the modern engine obviously would be better fuel economy , some drivability and of course the WOW factor under the hood, but let’s face it very few of us use these cars to as daily drivers all year round so the fuel economy and bit better in drivability isn’t a huge concern.
I feel as well as other Mopar enthusiasts that I spoke with that the aftermarket is not very price friendly to do such a conversion which is a shame. I spoke and seen the Chevy guys doing up LS motors and they have it so much better, they have everything to their disposal at prices far more reasonable than what the Mopar crowd is asking for.
Maybe if the Mopar crowd priced themselves better it would be a much more popular build and get the notoriety that the LS engine is getting. Maybe that is the main reason why Chevy is so popular and are gaining on everyone all the time.
I will keep an open mind about the build for the future.

After reading just a few of the threads in this section and looking at what is involved, and the prices, I agree 100% with your assessment.

Sounds like a $7-8,000 investment to do it right, and yeah, you could build a Hell of a RB motor for that amount with easy off-the-shelf parts.
