440 Build Change of Plans

The only thing I can suggest is to not overthink a truck engine for a tow vehicle too much. Maybe build it to have plenty of torque with a nice flat curve. You may not need the TF 270's on that type engine, if the advantage of them is at higher RPM's and higher lift numbers. Put headers on it with quieter type mufflers so the exhaust drone doesn't drive you nuts on a longer haul. Good luck with it.
