72 k20 project

[ryanroo]

Thanks!

i got a few more parts hacked out.

the saddle for the tranny mount. i forgot to grab some metric nuts for the mount otherwise i would have snapped a pic with it up in place. the little pieces of flat bar(barf) are the ends of the crossmember and have threaded holes. their counterparts will be on the frame side and have clearance holes for 1/2-20 bolts. that will allow the center section to be dropped out and hopefully make removal of the drivetrain easier. plus i dont have to figure out a way to make the crossmember removable fromt he boxed frame....

here it is bolted to the tranny mount. the rubber mount is pretty wasted. it leans to one side and hangs to the rear because of the weight of the steel. hopefully i can get autocad set up soon here at home so i can draw my own stuff and get it cut with some expediency. otherwise ill be waiting on the draftsman to continue and finish this as well as many other parts...



Anyone know of a poly trans. mount for a cummins? same mount as GM and jeep used from the mid 80s till the late 90s at least but i can't find one for the cummins or any other application

Looks stout!

All I could find was poly engine mounts. http://polybushings.com/pages/2710.html

[Dieselwrencher]

I've used some poly mounts for TH400's on them with luck. Or get a poly cab bushing and use them. Maybe a radiator support set. I used 2 big round poly solid pieces on my Longhorn's trans mount. Those dodge ones suck, they break a lot.

[ryanroo]

Well, i have no real progress to show, had family out to visit over the 4th. i worked like crazy to get my patio finished before that. work has been totally busy bah blah blah. that and i have had a lack of motivation.

anyhow, Ryan, you will be pleased to know that i just bought a rebuilt 47rh from a guy up the road. its not a total crazyass hotrod build but it should work for me for a while anyhow. i can toss my computer in the dumpster!

[Dieselwrencher]

That's great to hear Ryan! I haven't done anything to mine except put it out side to cure............. I've been working on the burb instead. Maybe some day.

[ryanroo]

i found a little motivation somewhere.

tacked in and started to weld a few of the boxing plates for the rear portion of the frame







i should also be getting autoCAD set up here in the next few days. hopefully then i can finish the design on the tranny crossmember

Ryan

[Dieselwrencher]

Looks good buddy!

[ryanroo]

finished the welding. i still have to shear the little parts for between the crossmembers

[FRENCHBLUE72]

Nice build for sure id love to put a cummings in my blazer but thats waaayyy down the line... I love colorado my pops lives in kremmlin out in b.f.e.

[ryanroo]

after a nice 6+ hour round trip through the beautiful San Juans this is in my garage. its beginning to look like a tranny shop in here. i have a TH400, 4L80E, SM465, three np205s, a 47re, and now this 47rh in here. there is also a dana 70-U-2, gmc dana 60, the dana 80 and ford dana 60 front in the truck as well as the NP241.... add the 454 on the engine stand and the np200 from the jeep and its a nice round picture. its a wonder i have a wife anymore

Nice score on the 47RH! Start selling the extras to get a good torque converter.

i am like the crazy cat lady with parts, i just cant seem to get rid of any. only collect more. that list was just what is in my garage in CO. there is still a decent pile back in iowa at my grandmas. i have a problem. now that i think about it, i have a pretty darn good set of doors at grandmas that i wish i had here for the truck....

the guy i bought the tranny from gave me a core TC and i didnt even look at it till i was home. it is a non-LU from i dont know what. either a 727 or a518. i have the core from the 47re so that is no problem. i think i will call Goerend for my TC. just another cool grand.... jesus this stuff gets expensive.

i am just glad the drivetrain is pretty much sewn up. i just have to do the seals on the engine and it could be started and ran. very tempting.

i also finished(with the exception of a few little bits) the frame boxing in the rear tonight. hopefully i can get the bed soon. then i can fab the fuel tank. for some reason my wife has been hung up on the fuel tank so if i get it out of the way maybe she can quit stressing over it

Ryan

[Dieselwrencher]

If you want, I can get you a deal on a billet triple set at what ever stall you want. Just let me know.

[ryanroo]

Thanks!

i'll look you up for sure when the time comes

Ryan

[ryanroo]

finally got all the little bits welded up.

i have some areas i know will be receiving more fab work and left those unpainted. and i will probably have to grind paint in a few areas but i like seeing it black so i squirted it where i could...





this is the funny little area where the frame rail has clearance for the shocks in stock form. i had a few different ideas on what to do but in the end this is the one that won the day.

[Dieselwrencher]

Are you going to leave the shock mounts on the D80 alone, and just mount the shocks according? I think that is how I'm going to do it on mine.

[ryanroo]

i think so, i don't really have any reason to change them. the only thing that i think may cause issue is the plans i have for traction/torque arms. the passenger side shock may or may not interfere with that. i will have to cross that bridge when it comes.

Ryan

[Dieselwrencher]

We still put traction bars on dodges with out issues. I plan on putting a set on mine too. If I ever get that far..................

[ryanroo]

i finally got the transmission mounted. i have to finish the thing, as usual but it holds the damn drivetrain up.







i'll finish the welding later after i get back from the gym...

ryan

[Dieselwrencher]

That looks awesome!

[ryanroo]

Thanks

i did some welding on the tranny x. still need to pull the center section and finish welding it and weld in the rest of the transitions from the frame to the center section including the "boxing" plate for the outside. pictures will explain that better when i actually do it.

in the interim, i made up some gussets for the 4"x3" tube crossmember that i replaced the factory one with behind the cab. i may have gone overboard but at least i know it should be rigid





ryan

[Dieselwrencher]

Go big or go home huh? I think all of you that box these are going nuts. Ha Ha I had a 70 K20 I used to pull with a 550hp 396 and I was really surprised how well the frame held up compared to the 73 up frames. I might box under the bed of mine some day, but for now I want to get it going. Keep up that great work!

[ryanroo]

i have never been accused of building to light... in a few places so far i felt like i was even being a little chintzy with the beef. then in others i know all to well that i'm getting it done and then some. i am curious what this heavy b*tch will do to the scales at the co-op when i get done. i just remember the bed hitting the cab with it all twisted up when i had the big tires and tall lift on it.

anyhoo. i welded the little plate into the cross member transition tonight.





needs a little clean up and paint once i finish the center section.

I'm sure it was always on level ground beeing babied too? I know it'll all help. If my frame wasn't as tall and thick as it is, I'd be more worried. But it should be fine. (We'll see.)
