Porting the Crossfire Intake on an '84

Well...of course CFI DOES have a fuel pressure regulator...any form of fuel injection does. It is just integrated into the rear throttle body assembly, so doesn't really "stand out" like a TPI regulator would.

nelson84...which lines are you talking about? The "original" lines are a combination of metal and rubber.

The original lines, can you use them or have to go to metal like the 85 vette?

Hard to say without direct dyno comparisons (which I did not do). If that were the only mod done, then sure the power band would move up in RPM. Of course that was not the ONLY mod done!
