Thanks for the info Denny. Good video of your drive. My truck is a Chevy Grumman step van 3/4 ton. I swapped in a 60 261 for the 235 some years ago. It was a rebuilt block, but the rebuilder had passed when I bought it. I'm going to use it as a food truck and it will be hauling but wanted a little more speed. The engine sounds strong, except for a front end noise that nags me. I will take the GPS with me today for another run to see what actual speed is. My wife and I are from Dekalb.
