Anders;
I know this probably isn't something you get too concerned about,but what does an engine that size do to your fuel economy? I'm building a '74 Chevy one ton long wheelbase flatbed duallie for a work truck,and am trying to decide on an engine that can be reasonably good on gas,and still have lots of torque and power. It'll be running empty some of the time but will be pulling a loaded car trailer and loads of steel for 300 miles often. I have a 355 for it now,but I don't think I can pull enough power from it to do what I need to do. I'm not seriously considering a Diesel for it because of the cost of purchase and installation. So I'm wondering if a big Caddy or Olds can be set up to get some decent mileage in a truck this size.
