Ok how hard is it and what kinda work am I looking at. I would like the 700 cause of the overdrive. Or would I just be better off looking for a NV4500 Im just having ideas thats all. Anyone done this before??

if you go with 400 you should be able to use you're transfor case, but will have to get a 400/208 adaptor.
shafts will have to be lenthed and shortened.
will need a auto colume or floor shifter.

my dream is an nv4500 for a daily driver but $$$. Why you thinking of losing the 465? just want overdrive? personally if I had an 700R4 equipped rig I would be looking to throw in a 465 but thats me. 400 you won't have overdrive but you will have a good strong automatic.
Well dont get me wrong I love my 465 but after 5 years of shifting into just 3 gears I just get curious what its like to have an auto. Anymore Ideas would be great. How much does an NV4500 cost? Just curious

think of it this way...
why not change gears and or tires?
with the nice low and ok first gear alond with a good clutch you can run gear and tire combos that most people would run from with a slush box.
plus they are very durrable. i just swapped in a 465 to my 74. and i will be running 42 inch tires on the 4.10 gears. with the doubler and the 465 my crawl ratio will still be nice. plenty to push 42's around the rocks, mud, or snow.
and still have a nice highway ratio.
for example, 2460 rpm at 75 miles an hour. not bad since thats right in the middle of my powerban. now, will i go 75 with 42's? well, knowing me maybe a few times....
anyway, what i am saying, you can spend a nice chunck of change in more than one way. are 42 inch tires for you? maybe maybe not. but maybe a taller gear or tire would be nice as well. ya got the gears in the tranny to get ya going and keep ya at speed with a taller gear.
just an idea for ya to ponder.

Seventy4 is right.
I've got 33" tires (no lift) and 3.42's. The truck is geared *perfectly*.
NV4500 is no better than the 465 (at least in this respect)...same horrid gear splits, just an additional OD, that isn't even as effective as the 700R4 as I recall. (.75 vs. .7 for 700?)
If you do some checking on RPM calculators, you'll see that you aren't much over 2000RPM with the 33/3.42 combo with 1:1 final tranny ratio, and as I said, I don't think cruising RPM gets much better than that, although as soon as I can find a free rear 10 bolt, I'm gonna try 3.23.

I don't know whats wtih my 465 and my gears but its geared horriblly. I have to start out in creeper gear always. I did with the 305 anyway. I think with the new 350 I will have enough torque to be fine now. But in 4th gear with my foot to the floor it just sits there. If was doing like 65 when i got out of 3rd within a mile of being in 4th I will be doing 55. It actually loses speed, I don't get it.
Well, thats going to be rear gears, engine, and any variances in the vehicle itself. All the 465's are geared the same, so thats not the problem.
I can idle mine from 2nd through 4th from a stop without a problem. (350) My dads truck, with a 454 and a cam not good for a truck, (poor idle) can't idle away in 2nd, you have to pop the clutch, and it has 4.10's.
From 60-85+ takes NO time in my truck on flat ground if I leave it in 4th. It's obviously no speed demon, but it would blow my previous K5 (305/700/3.08/31") away. (that thing couldn't go faster than 85MPH on flat ground)

sounds like my k5. It tops out at like 90 going downhill. Maybe 85 on flat maybe. I know its the engine and gearing and not hte tranny. The guy I got it from said it was 3.73 gearing but I don't believe him at all.
Find out what the gears are. If they are 3.08's, I think I'd be looking for some 3.42 axles. Since you are running the same tire size and tranny I am, I think thats as (numerically) high as I'd go and still like the way it ran on the freeway.

Sled dog,
I would check to see what gearing you have. I am running 3.08's with 35's and a weak 350 and I can maintain 70 at 2100 RPM's on the interstate. I had symptoms similar to your once and I traced it to a melted plug wire.

my 305 was horribllly beat, puting in a 355 in a week or so, see how it is then.
