It is a better engine design than the older stuff but at this point in my career I'm not going to switch. I have decided to ignore SB and /6 engines from now on and just focus on big blocks. I see the G3 as a superior design to the big block but I'm not interested in building one for any of my projects. I have a 5.7 in my Dodge Ram pickup truck and I'm happy with it stone stock and doing its thing.
