Yeah, wasen't sure when the 320 EFI came out (87 or 88), I knew they had a carb version called the tempest previous to the EFI and was rated at 300 horse.
At anyrate, yeah that motor pushes that boat really well and the hull takes it no problem. I run consistently at 63gps and have seen 66 with a little tale wind.
Now I just have to build 2 of them and throw them in a 272 and I'll be pretty set for where I want to be!!!

OK, this strikes me as odd. The 311 sheet and the 303 sheet are both Sr1's and both have twin 454 mags bravo's (365hp).
The 311 is 3" narrower but 150 lbs heavier and 2' 9" longer with the swim platform.
I would have thought the 303 would have gotten better "milage", but the numbers posted by formula do not show that. Best for the 311 is 2.1 mpg at 28 mph at 2500 rpm. The 303 was only 1.7 mpg.
The 311 was faster and more fuel efficient than a boat almost 3' shorter? Did they just screw that boat up?
