W350 Crew Cab - The ultimate first gen - Pics and history

[HHhuntitall]

Robert, did my cam two days ago in the '93... . I ended up using my 3ton long ram jack, loosening the front radiator support from the frame, and pushing the whole front end over... . my cam gear came out catching over half of the radiator support!!:{



But now, the Colt Cam Maximum Fuel effeciency Cam is in place and bumping accordingly in between the POD injectors!! And you want to talk about fun!! I should have done this a LONG time ago!!Oo. I had to stop and pick up all the crap I had on the back after I left the gate..... I really wasn't ready for that kind of response to a throttle push!!! I'm really excited about this project!!



Thanks for the tips and motivation!!

 

[RSchwarzli]

Well I am glad to help! That sounds great! I can hardly wait to feel what the cam feels like! I have always heard it is fun, just have never done one and experienced the results!



Makes me want to do the dd. Then I think about the headache of the swap and the front end..... Maybe I will wait till this one is done!

Oh, from what I've gotten to know you, you're gonna LOVE it!!Oo. The '90 DD would benefit with a little better fuel mileage, and probably quite a bit of power... I was surprised what it did to mine. After I made the run, I had to get in it and try it again... I couldn't believe it was that good! It's not the same truck, at all!! It's always been kinda noisy, with the factory timing, which was advanced a little, but now it's quieter, even with a big hole in the floorboard from where I moved the shifter(It's covered with a piece of plywood and a cup holder on top, no isulation... yet)!! It always sounded like the throttle cable was wedged between the cab and engine block, and seemed to vibrate under your foot when you pressed on it, almost like it was resisting. Now, it just moves out like a bullet, no arguments. I've built some stroked 498ci Chrysler Wedge(RB) motors that did'nt make the torque these cams are!! I put a Piers Quickspool in my '03, and it's a monster, now. No programmer, just the cam, a bigger turbo, and some DDP 60hp nozzles, and it runs like it had the 60hp Smarty programmed on it!!! Timewise, I don't know what to tell you, but I'd slate it down the road when you get the UCC running! Definitely worth the money!!

 

[HHhuntitall]

I just put a calculator to it, and running the upgraded cam in my '03 has saved me $0. 041557 a mile, as it usually runs around 5mpg better... . at $3. 79gal, that pays back pretty quick on a $400 camshaft... . 9,625. 33miles to payoff... . quicker if fuel goes up any more.

 

[RSchwarzli]

I am wanting to cam the DD bad enough! You are not helping matters here Mr!! :-laf

 

[RSchwarzli]

You know, kinda bummed this truck is not ready for the trip to Warren and Cummins tomorrow!



Next round I guess!

NP205 adapter

I must have missed it, what did you use to adapt the NP205 to the 6-spd transmission or was it a bolt up deal?

 

[RSchwarzli]

It was a direct bolt up. You may need to shorten the coupler that goes on the trans output shaft and the T case input shaft, or you can leave the trans rear seal out and then you are good (thats what I did).



Other than that its a bolt on more or less.

 

[MikeW.]

Thank you very much.

 

[RSchwarzli]

Any time sir!

 

[ENafziger]

Any update pics? How close is it to hearing it run?!

No pressure, just asking

--Eric

 

[RSchwarzli]

Yes, I have pics. Have been slacking though and not a huge amount of progress.



Pulled the T case out and did a full bearing and seal rebuild. In the end it likely did not need it, but better safe than sorry. Was the only high mileage item not yet rebuilt.



I do have pics. I will work on uploading them.

I'd actually be really interested in the pictures of this. Had you done a 205 rebuild before? Did it require any special tools? Where did you get the rebuild kit?

I'm likely going to have to pull my tranmission and transfer case soon to put a SB DD clutch in it. They have both been leaking, and I'm thinking I'll go through them while they're out.

No. Had never rebuilt one before. Special tools, not really. The biggest pair of snap ring removers would be a greatida! I picked a 20" long pair up and found that I could have used a slightly bigger pair!



I would say for you do go through them. In the end for me, I did not really need to. But as I had everything apart, you know dang well I put all new seals and bearings in! :-laf



I will get some pics uploaded soon for you. I have most stes of the process documented.

 

[RSchwarzli]

OK. The pics I have been promissing for a long time!

Empty case:

Clean off the magnet! You will be surprised what you find on it!!

Watch the little needles... they will all fall apart when you pull it apart so this is what is should look like... .

NOT like this:

Install the gears. The fun part is getting the gears and shift forks all liked up to be able to put the lock rails in. Will make you develop a few new 4 letter words.

Boom baby!

In my case the end cover does not go back on as the gear vendors gets attached, but still gives an idea.



Special tools are a few long drift pins, and HUGE snap ring removers. Also needed is a 1 5/16 socket for the main shaft bolts. If you look at the side of the bench in a few photos you will see the tools I used.

MAN!!! They just don't build things like they used to!! Heavy, tough, less moving parts, and just down right made well. That's a thing of beauty, right there!!! Thanks for the post!! Makes me think of McGaggen's slogan,"I'm lovin' it!"

 

[MikeW.]

Outstanding, thanks for the pics. Reminds me of rebuilding a Muncie 4spd for the first time on a work bench, used the grease on the needle bearings trick there too.

 

[ENafziger]

Well, almost another month has come and gone... any progress to report?

--Eric

 

[RSchwarzli]

Eric - you are funny! :-laf

No, actually no progress at all on the truck other than parts collecting. Summer is a busy time for me so I don't tend to get much done on projects like this. I don't see much happening on that till Octoberish as too much to be done on house, yard, etc before. And add in a 5600 conversion of the 1990 somewhere in there... .

But things like SBC hydraulics kits, turbos, interior parts, etc are arriving weekly! Should prove to be interesting one it comes time for the final run at assembly!
