How close are the engine mounts on the 4200 compared to stock 250 or 261 mount locations? I'm looking at a used 4200 engine and transmission (4l60e) came out of a wrecked, low mileage (5000 mi), 2005 Trailblazer that has the ecm and wiring but don't have a lot of time to do major fabrication work now. The printed specs say the length and width are fine for a '58 Chev.
