5.3 has plenty of power in my opinion. I tow a 5500 lb travel trailer with mine in an S10 Blazer. Will accelerate pulling very well. 4l60e tranny with extra cooler, single 3 inch Flowmaster 50 series using 98 fbody manifolds. This is a 2005 5.3. I have 3.42 gears and tow in overdrive all the time. Its being pulled now to be put in my 68 C20 so I can take my motocycle with me too. I recommend it with no questions. Pricing is better on them as well, and you can get them tuned to put out even more power. Also,I will be going with modified truck exhaust manifolds or Doug Thorley tri-y headers and would hope for a little more power. Good luck with whatever you choose. also good gas milage from 5.3.
