Hey Folks, I've been searching all over the NET for info on this situation. I have a 2014 Sierra 1500 Denali 4x4 equipped with a 6.2L and the 6L80e. I'm looking to swap in the 8l90 and would like to know what it will take. The engine set up is capable of producing over 1100 hp however, I'm restricted due to the transmission. Any assistance would be appreciated.
