Crazier swaps have been done successfully. Sounds like you got the background to pull it off without a hitch. Looking forward to seeing it.

I saw a 70 GMC long bed on ebay a while ago that had this swap. The truck looked great afterwards. If I remember right, all he had left to do was cut the rear frame rails. The guy was in Arizona. I remember asking him what size tires he had on it because it sat just right imo. He had Ford steel rims and I can't remember what tire size it was. But it was cool. I will watch this one too as I have a C20 too. Good luck w/it.

Nice, also planning a body swap to a newer frame, nice to know that the suburban looks to be close. Looking forward to updates.

BigrobDog · 03-10-2013, 12:51 PM

BigrobDog · 03-10-2013, 12:59 PM

iv got to questions now do i go and build a flat bed on there are fab that bed on , and since im using that tbi engine im not sure yet how to wire this all in will i be able to use that same alternator.because i think this one has a built in voltage regulator '

BigrobDog · 03-18-2013, 08:42 AM

just about got her all done . only been working on it a little bit on the weekends so i dont get burned out , all I got left to do is move my fuel tank forward because the suburban frame is a little long , so i need to move the gas tank forward and cut the frame remount the bumper.or those fuel lines under a lot of pressure . if i cut them and shorten them can i put back together with rubber fuel line, and i am also waiting for my wiring harness for the tbi.will the harness have the connectors for the 700r4 trany . well here some more pic

BigrobDog · 03-18-2013, 08:46 AM

redneck randy · 05-31-2014, 11:24 AM

Hey man sorry if i did this wrong, first post on here but im getting ready to attempt the same project with my 69 besides all the fuel injection. But i had some questions.
1. Did the cab and front end mount to factory cab mounts on the frame.
2. Whay body mounts do you need. And did you have to use a body lift as well
3. How far off are the wheelbases?

Thanks in advance!

redneck randy · 02-17-2015, 10:17 AM

I took factory mounts off frame bolted on suburban frame. Did use 2in body lift frame is higher in rear. I off set front wheel base is 2" longer still useing factory suburban fuel tank

Justin@EntropyRad · 02-17-2015, 10:27 AM

Looks awesome.

Randy..did you happen to buy a lifted grey burban a few months ago from a guy in Indian Trail?

redneck randy · 02-17-2015, 10:29 AM
