One big difference you guys are neglecting is fuel economy cruise speeds. I have a 357 with 420s and I routinely go boating with an OSO member who has a 382 with 500EFIs. Sure he has a little more power, and top speed is about 10-12 mph faster than my 60mph top.... but he's able to cruise at around 3200 RPM when I'm at 4000 for a 40 something mph cruise. To me that would make 45mph a lazy cruise instead of having the secondaries starting to open. The boats are obviously not drastically different, but the 382 hull is obviously a little faster in smooth water.

I'm guessing your 357 is spinning 3 blade vs the fastech spinning 4 blades, plus an older 420 set up usually involves a transmission vs a non trans Bravo set up. Although the steps are small, they must give a little advantage over a flat bottom. Too bad Formula never changes anything to keep up with the times and technology with their hulls. Imagine a larger step like Fountain or Cigarette. A 700/NXT 39 Top Gun runs 100-103 stock vs a 382 with 700/NXT in mid 90s with the same 18 year old hull on the 382!!!

Lots of variables in there beside claimed hp: x dimension, props and set up, has the bottom been blueprinted/tweaked, weight (as noted earlier), etc. Plus these are production boats and every one is going to be a little different.
