2014 5.3L -> 2020 3.0L

Traded and upgraded yesterday! First of all, the 10-speed transmission is unbelievable. Same can be said for the 3.0L Duramax. Smooth & quiet. The Duramax is full of torque, again very impressed. The cabin is huge, tons of interior space. Two car seats easily fit.

 

Very fair deal from my local dealer, enjoyed working with them on this custom ordered truck. I ordered it on 6/25 and took delivery 8/26.

I did mostly the same swap. 2014 5.3 ltz to a 2020 rst 3.0. I love the new truck but i liked the 2014 interior better.

congratulations! Very cool.

 

I have a 2015 and really want to trade for a 2020 but unsure of which to choose 3.0 or 6.2?

I really don't tow much and not too worried about fuel economy

All feedback is welcome

The 3.0L Duramax is the way to go for MPG, and comes with a much better powertrain warranty.  I chose it for these reasons, with the additional expectation that the diesel would last longer, experience less issues, and have better resale.  All of these are just assumptions on my end.

 

The 6.2L is the way to go if you need max towing capability and horsepower (thinking 0-60 times here).  The 6.2L also has much better aftermarket performance support.  Can't get any performance parts for the 3.0L Duramax right now, even a year later after the engine first debuted.
