More question on engines and rear Axle

I have my new tow vehicle truck search down to two different models
what would be the better work horse.
1. A 5.7 liter V- 8 with a rear axle ratio of 3.55
2. A 5.3 liter V-8 with a rear axel ratio of 3.42

Both have speed automatic transmission

  • Truck 1. is the obvious winner for pulling a load. Option 2. is a grocery getter IMO.
  • Don't know what size trailer you are pulling but I would compare the yellow sticker payload ratings as well.
  • IMO apples vs oranges in towing/working output.
    I wouldn't consider the very small 5.3 gas engine a work horse. Its used in 1/2 ton trucks and suvs/sports cars.

    The 5.7 Hemi is used in 1/2 and 3/4 ton trucks and has more hp and especially torque numbers for a small work horse engine.

    Yes, one is a Dodge, and the other a Chevy.
    and they are both 4x4's which I need.

    The price is almost identical
    The Chevy a tad lower

  • They are both new 2013's
    and I forgot to put the "6 speed" for both of them above

  • not posting the year or what transmisson, makes it difficult.

    the older 5.3 had a 4 speed trans which required lower rear end ratios. but the newer 5.3 comes with a 6 speed trans, which allows for it to run with a higher rear end ratio.

    not enough info.
  • What year?

    Gear is virtually the same. 5.7 s/b better at pulling unless it is much older.
