19Lb. Injectors
I've heard that these are a popular swap. I am putting the finishing touches on my 300 and have a set of 19s laying around from a 5.0L Crown Vic engine. Would this be a worthwhile swap? It's a stock, balanced, 300 for a 96 F150. I honestly have no real plans to modify it further than a free flowing exhaust with no cats and an O2 sim for the after cat O2 sensor. I'm afraid it might run rich. Any suggestions?

u'll need a fuel pressure guage and adjustable pressure regulator. according to silverstreak he said they didnt help much. also accorings to strangeranger the stock ones are good to about 162-18ish hp depending on the pressure. i would honestly say, u'll be fine w/o them. installing them w/o the reglator will over flood the engine.

I thought so, but I wanted to get a second opinion. I know that my six also runs 45-60 psi fuel pressure, but the V8s run 30-40 psi. I didn't know if I should switch to a V8 pressure regulator if I did the 19 Lb swap, but I'll just leave well enough alone. She won't ever see over 3,500 RPM anyhow.
