Sorry the follow up, but I failed to completely state the possible issue. Looking at the charts, the trailblazer had a 53/47 weight distribution, and approximately 2446 pounds on the front end. I looked up the curb weight for a 1958 chevy pickup and it listed 1650 pounds on the front - approximately 800 pounds less. This would explain the stiff ride when you were coasting. Can't wait for a video of your truck running.
