71 c30 project
 

hey guys i have been curising this forum for a while, I have recently bought a 71 chevy c30 c&c. Been working on it when i can, between kids and job i dont have a lot of time. So far I have pancaked the from crossmember and cleaned and rebulit the whole front suspension. Made upper and lower bag mounting plates and cups. Now here is where i need help, i have a 12v cummins in my shop that was slated for my 85 k30, but i think i want to put it in the 71. What size air bags do you guys think would be right for this? I have some #3800 bags already but mocking them up in the front suspension they look hugh, but i know im going to have a lot of weight up from. wondering if i need to go with #2600 bags. I would be very grateful for any advice!

This is the truck the day I picked it up. I will update as often as i can with pic, thanks again.

I dont have any answers but Im in for your build as I may learn some things .I just bought a 72 C30 flatbed Im playing with ,just blew a front tire on the way to get new tires on Tuesday and had to have it hauled on up there as I had no jack or spare .I hope to get mine back home tomorrow and play with it some more.I look forward to your progress .

Re: 71 c30 project
 

Thanks! hope your project goes well.

P.S. As new parts are bought/built, old ones will be for sale. Front disc brake conversion for you guys that have drums on the front.. pm me for details.

Slam specialties SS8 should do. I am running these on the front of my dually build because one day I want to do a duramax swap.

Re: 71 c30 project
 

Hey guys i know it has been a while since i have posted any progress on this thing. I have been mocking up the front end and ran into a few problems, i have to get smaller bags and now decided to go with a set of Porterbuilt front control arms. I have been collecting the pieces and parts i need to build my rear suspension, it will be something similar to unclematt's set for his c30, very heavy duty.

:metal:Very interested. Subscribed too see more

Re: 71 c30 project
 

Hey guys well I have been saving all the money I can so I could buy the wheels Ia wanting to run that way I could have them to mock up the rear suspension, motor location and anything inbetween that I may run across.. anyway I had about half the money saved for a set of milled alcoas plain I might add. When I was cruising CL in my area and found 6 of these for 2600.000 :metal:

That sounds like the town where I work (Waleska) ,you blink and you miss it.

Re: 71 c30 project
 

ok well things are coming together.. i called PorterBuilt today to order my control arms and all I can say is WOW! Those guy are the best, answered all my questions and got me set up with everything i needed! Can wait to get them here and painted and install. Then i can start cummins mock up..

Re: 71 c30 project
 

Well my porterbuilt control arms came in the other day, and man they look awesome! I also went ahead and got their hood hinges, top notch as well.. heres some pics they are 2" wider and ball joints set 1" forward.. im thinking about doing some dimple die work on the upper arm before powder coating them..

Re: 71 c30 project
 

Very Nice!

Re: 71 c30 project
 

Should be a very interesting project.

Re: 71 c30 project
 

I'm tuning in to this one. I like the direction it's going.

Re: 71 c30 project
 

Mr Moose,

With your control arms being 2"wider aren't your wheels going to be sticking out of the fenders? Especially if you have those big rig wheels that will need adapters putting you out even further.

Just wondering........... Flat67

Re: 71 c30 project
 

With the 2" wider a-arms you run standard 3/4-ton or single wheel 1-ton rotors.
This combo will tuck these 10-lug semi wheels!

Re: 71 c30 project
 

Thanks lolife99, this is exactly what im doing. I saw this trick on dinos63 dually build, which if anyone reading this hasn't looked at or heard of this guy look it up he builds amazing trucks!:metal: Anyway thanks for all the posts, more updates soon!

Re: 71 c30 project
 

Awesome build. In for the rest of this build.

Re: 71 c30 project
 

Hey got a question for you guys, are the front crossmembers in the 1/2, 3/4,& 1ton trucks all the same? I know the control arms are a little different but could you bolt a c30 crossmember into a c10 frame?

Re: 71 c30 project
 

If you are going to use a 67-72 C10 frame,... I just bolt your C30 a-arms to the C10 crossmember.
I think all 67-72 crossmembers are basically the same.
(there are minor differences in brake line mounting tab locations)
