Got my original 78 GMC aligned today. Had the 78 GMC that I put the 1 ton in last year both together. Had some road race friends over tonight. Good drivers can read the car, and track by the feel of how the car handles. The key to winning is having the ability to feel each tire. Can tell if each spring, shock, and other suspension component is performing to the track surface at that temperature. They can even give you a good idea of how much fuel that's in the tank by feel. I'm fairly good at feeling the car, and track. But not good enough to win all the time. So with these kinds of drivers at hand. I thought a comparison might be fun. I told them to drive each GMC the same 5 mile route at the same speeds. I told them nothing of the differences between each coach. Both 78 GMC's. I just said that I wanted feedback on how each GMC handled. Or if they handled the same. Remember. This wasn't very scientific. But with very good drivers. Every one of them liked, and were imp
ressed with the original GMC's handling for a vehicle that big. Statements on the one with the 1 ton conversion. 4 of the 5 drivers felt that there were some suspension geometry issues. 3 didn't like the handling at all. The other 2 said that they felt uncomfortable with it. And felt that they wouldn't want to travel a long distance in it. You must remember that these drivers are trained to be very very sensitive to the handling of what they're driving. And having two GMC's to compare with in 15 minutes. Can make things stand out more. I'm NOT saying that the 1 ton conversion is bad. It's just some observations. Last year when I installed that 1 ton kit. I made a model of it. Then a model of the original. Yes. I did have some geometry issues with the 1 ton kit. Sorry. I'm a suspension nut. GM should have put a ground finish in the bearing bore. That was the weakest link. After all. It's worked for 41 years. Not too bad. As for tracking. A lot of vehicles don't have the same
track front to rear. For me after making the models. I'm sticking with GM's idea. Please don't shoot the messenger. ( GRIN ) I just thought it was interesting. Bob Dunahugh
