Been looking at 6.2L Chevy Silverados to replace my 5.3L. How much better of a job would the 6.2 compared to the 5.3 do especially when it comes to towing up mountains. My 5.3 really struggles with my...
New 8 speed 5.3 out pulls my 2016 6 speed 5.3. 2016 is considerably better than the 08 4 speed and 01 5.3 I had. Both old ones had 3.73s, 2016 is a 3.42 and the 2019 was 3.23 or whatever that ratio is. 6.2 10 speed will blow away the 2016. Based on an Escalade I rented. It was a rocket.
I put about 10k quick miles on a 2019 5.3 8 speed and it did not struggle with an 8k flatbed in the Cascades (low altitude).
