85 GMC Sierra Classic 1 Ton Crew Cab

[Mattman2010]

Well I have a somewhat small update. Oh wait, I mean a big update. Met up with Ryan (DieselWrencher) and finally picked up my motor and trasnfercase. I also got a cracked NV4500 from him that he is letting me borrow it so I can get the mounts made and then I will go get the good transmission from him later.

CUMMINS!


NV4500 and NP205


Still have to find a bell housing for the transmission. I did get an adapter plate from ryan also but we are not 100% sure if it will work or not.

Sweet!

What intercooler /radiator /fan do you plan on using?

[Mattman2010]

Good question! I have no clue! Opinions? haha I am planning on getting a new 4 core bb radiator and running 2 electric fans.

[1985-GMC]

I'm not real sure in the intercooler but I think i'm gonna use one from a powerstroke, like this I guess: http://www.ebay.com/itm/7-3-powerstr...add61f&vxp=mtr
Ryan will know what fits. A chevy 4 core should be good but I'd try to squeeze a mechanical fan in there first and use electric fans as a last resort.

[Mattman2010]

I think he said that the dodge mechanical fan would not fit on this because it was out of a freightliner, and their fans wont fit into a regular truck.

[1985-GMC]

How far apart are those bolts on the front pulley, will a chevy fan fit on it?

[Mattman2010]

dont know, have not really looked into it lol

you can always get a dodge fan bearing off ebay or something so you can run the dodge fan. I have one from a 92-93 intercooled dodge as they were a little bit shorter, and gave more room for the fan. they are hard to find though usually.

[Mattman2010]

I was told that I would have to get all the dodge brackets for that to work because it moves the belt closer to the motor so all the brackets would have to change.

Well I picked up some steel monday that was scrap to use to box the frame. Itsf6 pieces of 10" by 5 ft 1/4 in steel. Should be strong enough.




Last night with the help of a couple buddies and my dad we were able to get the cab off of the frame so that i can box the frame easier. Just gotta move some stuff around in the shop and push the frame back in.

Yes, if you switch your fan hub for a dodge version, you might as well get the dodge alt brackets too. Because yours won't work with the dodge fan hub.

Nice progress and keep it up man!

[Mattman2010]

Things have been busy with school so things have not been going as fast as I was hoping but I did get some shop time today.

Got the sleeves for the steering box and got them welded to the frame. Still need to drill out the boxing plate to fit around the sleeves.



Also made a new cross member for the front because the stock one has to be cut up to fit the 12v in so I decided to make a new cross member so that I can try to mount the motor lower in the frame some.



Got more plates tacked in the frame. Getting close!


That is all for this update. Hoping to get the frame done the next time I get to work on the truck. Then it will be time to put the cab back on and start making the mounts for the motor.

[Mattman2010]

Started boxing the frame tonight. First peices are going slow trying to get the hang of it.

Thanks man!


As for an update I should have some pictures some time this week with all of the frame boxing pieces all in place. I replaced the front cross member because all the cummins conversions I have seen on these you have to cut the cross member, so I just cut it out and put a new one up toward the front of the frame. Ill be using 4x4x1/4 inch tubing for the cross member for the motor so I dont see a problem with having the front cross member mounted in the very front of the frame.

[1985-GMC]

Looks great man! Are you making your engine cross member after you box in that area, and are you going to sleeve the shock bolts like that too?

[Mattman2010]

Yes, the cross member will be put in after the frame is boxed. I am just going to weld the cross member in. As for the shocks I just welded the nut inside the frame.

[Mattman2010]

So today I got a few more boxed pieces made for the frame. Also welded all the nuts to the frame for my front body/spring mounts. Not going to final weld the stuff in till I get my bushings from Diy4x for the front shackles.



Shop is starting to get messy again. Probably need to clean up soon.

[Dieselwrencher]

It isn't messy enough yet. You need at least one more truck strung all over in there. Hehe! Keep up the good work!

Haha that's not even all the stuff I have. We also have sides of the shed and I think I have two trucks worth of parts stuffed over there lol
