You are very kind. The truck turned out as nice as it did because of the kindness and generosity of previous and current members of this board who were willing to teach and share and encourage and in many cases inspire. It's about as cool a place as there is on the internet and whatever good I can put back into it, I'm happy to...because it feels like I always seem to get more than my fair share out.

Hell yea! Beautiful truck! Wish my short 69 looked that good... or even my K20 for that matter!

[DeadheadNM]

Looks great!

[Ol Blue K20]

Love it, what a beauty!

[davischevy]

Beautiful.

Very nice.
All stock?

Very nearly. The color is tweaked. And though nothing on it newer than '71...It's got tilt, front disc brakes, TH350/NP205, AM/FM radio, white wheels and P03 caps. None of which were available on a '69 or at least a '69 4x4. It also has 3 point seat belts. Otherwise we tried to be pretty faithful to a factory style restoration.

And Thanks.

Very nice . Excellent additions.

Love those shorties.....

[rowdy11]

Always nice to see a fellow 70 shortbed 4X4. Welcome! Any plans for the truck? Sure looks good as is!

I’m hoarding parts for my ls swap now. My plan is to keep the 465/205 in there place and mount the 6.0 wherever it needs to be to keep the stock driveshafts in place. I know that doesn’t exactly help with the od transmission in this case. For my 3100 I’ve got a turbo 400/205. I’m gonna 6.0 or even 8.1 swap that one with a 4l80E and the turbo 400 spec 205.

I've got the 6L90 with my NP205 (kept the stock trans crossmember and location but fabricated a few mods). Happy to share any lessons learned as it's a bit harder to find LS swap info with a transfer case mixed in on the board.
I'm wiring my LS engine as I write this...prepare for a lot of work with an LS swap but I get more and more excited each day I make progress!

I’ve got a 4x4 6L90 that came with my 6.0, I’ve thought about that route but man it’s pricy getting the 205 behind it. It’ll be nice when you get it all done. I’ve got an 18 Sierra 2500 with that tranny and it’s quite nice to drive. The 6L80 in my Camaro is every bit as good drivability wise. The low first and second gears In both of them get you out of the hole pretty well.

Hey Rowdy11...Had to read through all of your build thread before responding and now have a full page of new questions! Won’t ask them all now, but will definitely keep your offer in mind!
Gotta admit your experience scares me a little as I do not want to (or need to) dismantle my truck. That band saw action would be a challenge with the np205 in the truck.
I am hoping to keep the NP in place and “slide in” an OD Tranny and LS motor.
That’s sounding a little simplistic after reading your thread.
Maybe the Sniper add to the existing 402BB is more in the cards.
Sure appreciate all of the comments and offers for assistance !!!
6L90e six speed sounds awesome! Extra challenges with that set-up I am guessing?

You bet! Happy to answer any questions and promise not to hide either the good or the bad...it's been a big learning experience for sure!

MATING 4L60 TO NP205

I like the color combo.

That seems like a reasonable plan.
Questions;
1.crate LS or boneyard LS?
2. Turbo 400 spec NP205? Early GM NP205’s are not all the same ?
Thanks in advance!

Negatory on the early 205’s. I believe save the adaptor housings and the coupler setups, the (84 and earlier) turbo 350 and sm465 205s are the same. ie. you can take a 465 205 and swap the adaptor housing and the coupler between the tranny output and the 205 input and convert it into a 350 205. The turbo 400 205 has a larger input shaft and bearing that requires machine work on the early 350/465 205 case to work. Because a 4L80E is basically a turbo 400 with overdrive it’s not very difficult to mount a turbo 400 205 behind a 4L80E. Does that make sense? Basically the 69-84 gm TH350/SM465 205’s are all the small diameter input shaft cases. These will all be referred to as the figure 8 or race track case because of the way the tranny adaptor bolts up. Somewhere in the mid 70’s Gm introduced a 400 205 that is the same racetrack/figure 8 pattern But had the needed bigger input bearing. In 85 they switched to what is called the round 205 (again for the pattern that the tranny adaptor bolts to it) all round 205’s will interchange between SM465 and TH400 with the correct coupler and adaptor housings. The round 205’s all use a longer 32 spline input shaft and are stronger in that area than the older 205’s. If you can find an 85-91 square body K30, you’ll get this case regardless of the transmission it’s got in it. Hope that helps with the 205’s some. There are other changes to the 205 thru the years but these are some of the more major ones.
As for my 6.0 it’s out of a totaled 2009 Silverado.

Thanks so much for clarifying. I have a lot to learn!
So if I am following you correctly since I am currently running a t350 I can assume that I likely have a smaller diameter input shaft version of the np205.
Is the 700R4 the best OD auto for this NP? Or does one of the the newer electronic versions (other than the 4L80E) mate up well?
Thanks again!!

The 700r4 will work with the case you’ve got. Several people on here have done that conversion. The th350 205 is the actually the best one to have for that conversion.

[jjzepplin]

The 700r4 will need a new adapter type output shaft to mate to a 205. Not hard to do but make sure you get a 700r4 that is 1986 or newer as it is a stronger unit. The older ones should be avoided if possible. You can read up on it. I rebuilt my 700r4 with all B-M internals etc and was easy to install the new shaft at that point.
