225 turbo headers

No but I am basing my opinion on the theoretical advantage of EFI. Two identical motors, the EFI one will make more power, be more reliable and be easier to tune. No jets, no making the carb do things it was never designed to do, just change a few points on a chart and instant power. In addition, an EFI engine making that kind of power could be daily driven, it would be very difficult to set up a blow-through carb engine that would have good off-boost performance.

I am no engineer,and so I can't say with any authority, but I have read on several occasions, that there doesn't seem to be any significant total horsepower advantage. from a FI setup over a carb.

I would agree that the fuel curve under varying circumstances would no doubt, be more advantageous, so driveability would probably be better, overall, and full-throttle torque might well be improved in the lower rpms, so yes, if one has the expertise to dial-in a fuelie system that has the requisite tuneability, street driving and even mid-range torque would probably be better than with carburetion.

But, total power output (maximum horsepower) might not be superior.

That's just my two-cents worth and probably overpriced, at that!!:D
