2WD to 4WD
 

I have a 2wd suburban and i want it 4wd bad. Is this possible? I also have a 454 bb in the burb now. Will I have to down size my engine?

Easiest option is to find a rolling 4x4 chassis, and swap your body onto it.

You will likely be able to run the 454, but you may need to move it forwards a bit as some 4x4s had the engines in the I-6 position, which would cause some clearance issues with the firewall...

I know a lot of people say just swap chassis' but I still think that's not the easiest way to go. To me anyway. I was looking again through a jy last week. Since the holes are already there, still looks easier to just take off nose, suspend motor, swap crossmember, steering box & shaft and spring mounts, etc. Regardless of how many rivets to remove. Then deal with tc and drive shafts. Most definately the way I'm probably going to do it and use a 91 grille & rad support setup while apart. Personally, I'd rather clip the chassis behind the leafs than swap chassis'. But I've done clip jobs before.

Gabe you can always try searching the boards.
