no idea about the ratios. but when i was looking for the new engine for my truck. 80% of them where jeep 5.2's every one of them was drilled for it.

 

i thought they were all drilled?
is there any numbers/codes on the tranny there has to be something on there to id it

 

oh one way to tell wide ratio to narrow raito if its still in the doner truck or you kow what truck it came out of is:
wide ratio was used in the ram 1500's
narrow ratio was used in the ram 2500LD's

the 2500LD's with the 5.2 were only made up intill the end of 96 then all 2500 were 5.9+ meaning that there wont be too mant narrow ratios out there (the 2500 with a 5.2 wasent verry popular and was only in 2wd's i belive) and anything off of a 2500 after 96 will have a NV4500

 

Two or three more trans ID questions further down...

Crankshafts - I've heard the "might not be drilled" idea on several forums. I still haven't heard anyone say they have seen newer motors that weren't drilled though.

I'm wondering if that info is a throwback to the old days. One person that sounded knowledgeble said Chrysler had massive supply problems back in the 70s and used whatever they could get ahold of to keep the assembly lines running.
In mid/early 70s hefound (big block) Magnum motors out of automatic musclecars that were not drilled for pilot bushings but healso found 440motors from Chrysler Imperials that were not only drilled but hadbeen assembled with pilot bushings in them and used in front of an automatic!

Not sure but maybe some of these people are looking for a larger hole for a needle bearing PB but they are looking at cranks that are only be drilled forsmaller bronze bushings. I've heard people say those can be used with no problem and that one or another of the autopart chain stores sell brass bushings that will fit Mopars. Not sure if those brass bushings were what Mopar intended or if they are sold as an "adapter" to install manual transmissions behind motors that were not drilled. I had also heard ofthe bushings being machined to fit. Should work OK as there isn't really movement between the crank and input shaft.

Gear ratio -
Those 2500s LDs are only 2WD or were there 4WD 2500 LDs too?

Where those Daks 2WD? I doubt the Jeep would be 2WD.
Is the 4.0 bellhousing boltpattern the same as 3.9/5.2/5.9 pattern? I thought it was different but if the 4.0 got the NV3500 too maybe it's the same.

Going by application would be easiest true, but I'm wondering if there is a tag or set of numbers that I can ID them with. That way if the boneyard has already removed it and doesn't remember the exact truck or has misidentified the transmission I can confirm it before I buy.
Also, on that Geno's website it actually seems to identify three seperate NV3500s. Looks like a close ratio on the 2500 LD Ram, a wide ratio on the 1500 Ram and also an NV3500HD, also close ratiothat is slightly different from the other two.

Also - Does anyone know if theRam 2500s have markings or much better, anything in the VIN orbuild plate that identifies them as LD vs HD?
I figure if there is no external ID an 11 year old truck may have been through a few owners and the newer owners might not know the difference.
Even if they originally came with external LD/HD decals or emblems that might not be reliable if the truck has been painted or had collision repairs done with usedparts.
If the 2500LDs are only available in 2WD then it doesn't matter I guess. I def want to keep my 4WD.

Thanks again to all - I'm learning more every day.

 

i cant say 100% one way or the ither...but i havent ever herd of a 4x4 with a 5.2, the 5.2 in the 2500 wasnet common as it wasent that big of a seller (made th truck under powered like putting a 3.9 in a 1500) as a matter of fact the only 2500's with a 5.2 ive seen/herd of are 2wd reg cabs short or long box


i dont know too much about the NV3500HD, ive been learning more about it as we talk
here is a cupple listings of difftent pepoles combos moter/trans ive found
http://members.aol.com/meaneyj/joe2000.htm - has a jeep 4.0 with NV3500HD
http://www.pavementsucks.com/forums/...php?post=37772 - talks about a 318 (5.2) with a NV3500HD
however this thread talks about the NV3500 and NV3500HD being non-compatable
http://www.dodgedakotas.com/boards/gen/12763.html
best thing i can think of would be to go to the dodge dakota section of this site and see what they know about them as they would know more than me about it, if u do u should link this one to it and that one to this one so we can swap info


i agree i also think there has to be some way (maby in the s/n or p/n) but i dont know how to i know they have tags on the back near the output shaft but ive never looked closley at them


thats correct, the wide ratio on the 1500's will be by far the most common not sure about the HD thow again i dont know too much about the HD line

VIN yes If thevin's 8th diget is a 5 you have a HD 360, if it's a Z you have a LD 360, if it's a Yyou havea 318 whitch an LD in the 2500's
both HD and LD 360 (5.9) came with the NV4500 not the NV3500 only the 318 (5.2) came with the close ratio NV3500


there never was any external markings


id wanna keep my 4wd too again dont know for 100% but so far all ive seen/heard of is 2wd's

me too

 

WOW - I just happened to find this thread when I was googling for something else.

This seem like such a long time ago LOL

Through a really weird set of circumstances I ended up buying that supercharged 5.9 Grand Cherokee. Turns out the trans was actually an NV3550 out of a later Wrangler - which is fine by me.
(sweet ride - Vortech V2, Hi6R digital ignig box w/ retard, Sanderson Block Hugger headers and 3" to the rear...)

If I was going to build my own (and I'm still planning on converting one of my other ones) I'd go for the "Terminator AX15" as sold by rsgear.com and I believe the same spec trans is available through George at transfercaseunlimited, although an offroader might prefer the NV4500.

When I got it it still had the check engine light problem.
After a bit more research I experimented and... the ZJ is now running CEL free with a 98 Ram 5.2 5spd PCM! No modifications or re-wiring necessary.

I'm actually going to be using the "5spd pcm trick" on one of my other 5.9s that's going to be running an old school 727 (to eliminate the CELs from the missing 46RE tranny)

 

Anybody know how to figure average speed?

 

184.6 mph. pretty fast truck, huh.



60 min / 13 min = 4.65 factor * 40 miles = 184.6 mph

184.6 mph / 60 min = 3.07 mile per minute.

13 min * 3.07 miles/min = 40 miles.

 

I thought that sounded like bs and now I'm convinced of it.

 

They only had the 5.9 in the R/T models correct? I think your watch or his odometer must have been wrong cause otherwise you would have to have been averaging 185 mph.
