jodaddy is starting off with a positive reputation.
I have a 4.9/m5od/3.08's with 31's. It does 68mph at 2k. Hit a hill and it won't accelerate up it. If I drop it into 4th it runs at 2600 and will climb right up without losing too much speed. I think the 3.55's would put my truck in the sweet spot so I could use 5th and accelerate without having to downshift. So my coworker has a 5.0/a40d/3.55's and 235/75/15's. we drive around 90 miles to the job site. His truck seems to outperform mine. Neither of us push them real hard but his seems to pull the hills better. I think with proper gearing they are both suitable engines. Neither of us would do well pulling anything other than an aluminum boat.
