Hi everyone I'm new to the sight and enjoy it very much . Need a little help . My son has a 9-98 powerstroke with bad motor and we want to install a 01 motor. I find out that there's quite a different and was wondering if we could just use the block and heads of the 01 and switch the injector and other parts from the 99 to the 01. So we wouldn't have to swap the computers and IDM. and wiring harness. Thanks diesel-kiesel
