Wes here is my reason, it is not true that you are getting more torque at any given rpm look at the torque curves the 5.7 is much flatter than the 6.0 so thats why in his instance I am saying I would use the 5.7 for the fact that it actually does develop more torque at the lower rpm ranges. Here is the data you can see that at 2000 rpm the 5.7 is developing more torque. That was my thought process for his specific circumstance of low rpm cruising. I have a friend who has a Baja with the new 496 HO mags sweet motors but designed to be run at 5000 + rpm for power they have been worked on more than once under warranty and I feel it is because of how the motors are used high rpm's for sustained running on the lake. Cruise for him is 4500 rpm's at about 50 mph this is his second new Baja the 32 had multiple instances of blown motors and his 38 has been in the shop more than once. No he didnt do anything wrong that I know of but he has lost lots of time on the water.
