    • Yes, they CAN be too low. Truck hits the bump stops on one particular lump in the pavement here in town but is fine nearly everywhere else so I live with it - he has a Belltech lowering kit.

      • this is a great build thread with allot of great information on parts that work and went together smoothly. I'm personally not a big fan of super low vehicles, mostly because I've lived in the midwest my whole life and our roads are generally crap, so - lowered usually means fixing broken stuff.... ALOT. I hope you find the happy medium for this truck so it will fullfill your styling desires as well as retaining the utility of the truck. I really like the idea of air bags on the rear - that allows you to keep it lower than stock, but pump up the air and still tow safely, makes a lot of sense to me.
        There's always something new to learn.

          • I really like this project, however it has convinced me NOT to go LS in mine just yet.

            I'll save my LS virginity for phase 2

                  • My plan when I bought the junk yard motor was to run it for a while then swap it out for the rebuilt one at a later date - selling the JY motor to recoup some $. If I was on track with that plan the truck would have the new motor in it and the one in the truck would already be sold. As it is now, the motor in the truck seems to be running very well. It has 60lbs of oil pressure and probably enough HP & torque for what I want it to do. This has me wondering what I should do with the rebuilt mill after assembly. We've tossed around the idea of using it in the Caddy but we are not sure that is the right choice. We've got time to make that decision though as the soonest we would start blowing the Caddy apart is next year in July (after the 50's weekend). The Nova is also another option, but that runs so well and is so generally "right" I really don't want to mess with it that way.

                    Stopped at the frame shop yesterday and he is confident it can be fixed. Unfortunately, he is crazy busy and doesn't know when he can get to it. I am hoping for sometime before spring. My new front springs showed up a couple of days ago so that is this weekends project. Stay tuned for revised ride height pictures.

                        I had actually though of that. The Caddy is next up though and I don't have room for everything I have. Maybe I can trade the 5.3 for lumber to build more garage!
