My 2LT lost its head again and I do not want to deal with the 2LT anymore. Looking to do a LS3 swap (really any LS will do) and I wanted the manual six speed TR6060 GM trans with it too. These are all just thoughts and nothing is set in stone. What would be the best options engine, trans, and transfer case wise for my project? I like diesel a lot but gasoline is a more available choice in the US. Please leave recommendations preferably those widely available in the US, thank you.
