Carguy I will check into Fuel Pump PSI ratings
Solid engine mounts will be a matter of personal preference and intended use.
PSI, is not the problem. Yes, of course you need the proper pressure, for which the injectors were designed (which, may or may not be different for the 2.9L, and a '97 5.0L, you'd have to look that up.) The bigger issue is rated flow, or GPH (gallons per hour). A 5.0L is going to need a much greater VOLUME of fuel, particularly if it's modded, than a stock 2.9L-V6. You also want to make sure your fuel pump is rated at a little more then what the engine needs, as frequently running the pump at 100% of rated capacity will quickly wear it out.
As for the motor mounts, yes, whether or not you use the solid motor mounts is a matter of personal preference. However, as I said, if you do use them, then solid trans mounts are also required, in order to do the job the "right way", and avoid future breakage of the bellhousing/trans case.
