I have the 360 Mag and 5.7 MDS as you are comparing Sheldon:

I haven't towed anything with the 5.7, but to me, it runs like a 340 or the 426: only makes power when you scream their guts out. I spoke to a Guy who tows with the new 6.4 and he said it does next to nothing unless you get it to 3000 rpm. So, I can imagine your frustration.

My 360 Mag, with an open car hauler (approx. 5500 pounds) pulled 1400 miles in top gear no problem. At 1700 rpm the tach needle just stays there and it chugs along. It's impressive for a gas engine.

As you get more miles on this truck you will miss your diesel less and less: I know I don't miss my Cummins one bit. I drive the 360 Mag everyday and think it's a great engine, until I drive the 5.7 it's one-time-a-year outing, and it's waaaaay better than the the 360. And, that trans you have: no worries whatsoever. up

How many miles do have on it?
