I have no doubt that the engine will start faster if the timing is on spec or early. However, most folks with late timing won't think anything of a diesel that takes four or five seconds to start. They might consider this normal.
My comments on easily starting them with late timing are general remarks on the observations of others. In similar manner to a perfect set of valves that close precisely, IP timing that is on spec will provide an incremental benefit in starting capability.
The SD will start in less than 1 second at any temperature above 12F. It's got brand new valves and perfect IP timing.
