Andy...My last big block gas motors were 8.1 Liter and they were 385 HP...I think yours are 370 HP....you can usually find the performance reports by doing a Google search. The 31 I used to run for a friend of mine had a sweet spot at about 32-33 hundred RPMs and burned 26-28 GPH depending on crew and gear and conditions. My best guess is we were cruising at 22-24 knots, since he didn't have working speedometer od GPS at the time. Enjoy the boat...Bill
