 Subject: 5.2 TO 5.9 SWAP
IP: Logged
Message:
I am interested in swaping my 5.2 to a 5.9 using the short block offered by mopar. What all would I need to complete this using my 44re trans. from my 5.2. I have read that a new converter and flex plate are needed because of internal/external ballencing issues between the two engines.
also, will my stock fuel system and mopar performance PCM be able to support this??
Thanks,
Nathaniel

YOu will need a new PCM, Wire harness, headers because the 318 uses i OXY sensor and the 360 uses 2, im not sure but i dont think you will be able to use the 318 trans,,,,

I have heard the Mopar 340 engine stroked can rev higher and faster than the old 360 can.

if you use the wiring harness from the 318 for the 360 it will work with the 318 pcm, it may not pass emissions but that is not what you asked. you might want to compare deck height on the 360 verses the 318 as if they are not the same, there will be trouble in the matchup between the heads and the intake manifolds.

318s and 360s have the same deck height. The 360 will bolt up to the 318 trans, it's more a matter of the 360's TC possibly having a different spline count (though, I doubt it).
The other issue, of course, is the 318's tranny being up to the task...
As for the fuel system, it should not be a problem at all, as you can always upgrade to a 'larger' injector.
Computer-wise, why not ask one of the Dakota speciality shops if they could supply a custom flash for this swap?
CW is the person you should really be talking to.

I have been told that the 318 trans uses a
D-Drive on the converter and the 360 uses a slot.
So you couldnt use a 360 converter in a 318 trans

As far as the Trans. goes, it will be rebuiit and built up. What is a "D-Drive"?? I have Never heard of this. I swear I have heard that the only issues were because of internal and external ballencing issues. This i have been told would be fixed with a new TQ converter and Flexplate. Will the 44re bolt up to the block??
Thanks for the help,
Nathaniel

Yes, Nathanial, the 44RE/A500 will bolt up to the 360/5.9. The issue is the TC, which I'm currently researching for you...

I just talked to a tech from KRC and he said that only the flexplate needs to be changed. I hope that your info confirms this. I will be changing to a higher stall converter anyway. Anyone have experience with the Mopar converter??
Thanks Fubar512,

Nathanial, the 5.9's flexplate will bolt on to the 5.2's convertor.
The A518 that is used behind the 5.9 has a different convertor altogether, accoring to my sources.
Going to a beefier, aftermarket convertor on your A500 is a good idea.
The harmonic balancer is different (don't try to use the 5.2's)

Thanks for the info. I did not even think about the harmonic balancer.
I can never find any info on a 44re trans. Is this trans. commonly refered to as the A500??
Does anyone know of a good trans. rebuild/upgrade kit for this trans??
Thanks,
Nathaniel

The 44re is a beefier version of the 42re. Both are based on the A500 or if you want to go way back the A999. The 46re behind the 360's are related to the A518 or way back the A727. The 44 and 42re have a 2.74 first gear and the 46re have a 2.45 first. Basically the only difference from the a500 to the 44re is the a500 is hydraulic and the 44re is electronic.

Lee, it's been done before, with the appropriate parts, but the weak link is definitely the NV3500 tranny.
It may live just fine behind a stock or mild 5.9 (360), but if you start making serious horsepower, as you would with the 380 HP crate motor, it is gonna go bye-bye on you real quick!
You can try going the NV4500 route, and I've even heard someone trying the Tremac T-56 (6 speed), from the Viper.
Any tranny upgrade will require you to fabricate a tranny-mount, and possibly shift and clutch linkages, as well.
You should ask Marty from KFC or Bernd from Speedtweaks...they may have performed the swap you have in mind, already.

i just put a crate 360 (318-360 swap) in a few months ago, and broke 2 axles in half(????????). and now my tranny is fuking up on me. the 2-3 shift is hitting the rev limiter and bouncing back and forth(????) but besides that the 360 w/mods kicks asssssssss! i hit 145 against a z28 last night and spanked him bad! he was very surprised. the 360 pulls a lot stronger at higher speeds that the 318 and has so much fuking torque! itsd definatly a great swap!

LEE, I do not think the 360/380hp crate motor would work for the dakotas if you want to retain the fuel injection. because I do not believe the heads are the same between that crate motor and the magnum type motors. I could be wrong and if I am also interested in that crate motor also.
I believe that KRC has an article on a 6 speed swap or at least a 5 speed swap.
tman, what year dak and what tranny?? did you build your trans up to handle this extra power? any tips with the swap??
Thanks,
Nathaniel

My engine is going through the swap now, I have a 98 Dodge with the nv3500 318, I'm putting in a KRC built 360, the only change I had to make was the flywheel. Has anyone with a 5spd 98 Truck tried the Hypertech PP3?

my truck is a 92 extra cab, a500 tranny w/B&M tow and haul shift kit. i personally do not know how much the a500 will handle but i guess i'll find out soon. the swap was done professionally, but i know they had to put in a new torque conv. and a harmonic balancer, everything else came right off my 318(heads, ignition, intake, chip, headers,)

Does the Mopar shortblock come with a new oil pan? The pan off your 318 will not fit on the 360 because of the 360's bigger journals. Also if the shortblock does come with an oilpan you have to make sure it is the right style to fit a Dakota's suspension. You may just need a pan off a R/T. The advantage of the 44re over the 46re is that the 44 is lighter (accelerates faster) and has a lower 1st gear ratio. It is not as strong in stock form but can be built to handle even a modified 360.

Maybe I'm worng then, I was told once that the pan was different as the rear main seal is bigger on the 360 because the main bearing journals are bigger. Maybe they machine the main seals the same and just the interiors are bigger. I have also seen this posted on two or 3 other sites as well but they could also be just passing on wrong information. Maybe it only applies to the premagnum 360s and it was something corrected with the "magnum" conversion.

not sure on the magnum motors, but if they're the same on the bottom end as the old LA small blocks, the oil pans are different between a 318-360.

Message:
Must have been something changed for the magnum status. I did some more checking and the 318 and 360 did use different pans back in the 70's. Everything I read about what was changed for the 92 Magnum status had to do with making the 318's and 360 pretty much share all parts which was mostly to the 318's advantage. If they continued the trend from the 70's the 360 would have kept better heads, cam, intake, and exhaust manifolds to make better use of the extra cubic inches. This is one reason there is such a small difference between the HP on the 318 magnum and the 360 magnum while still stock. The 360 really should have a bigger cam, intake, and exhaust manifolds but it has to live with the 318 stuff for cost savings.
