Great information Dave! Out of interest, would your suggested 6.1 swap using the existing 5.7 tuning include using the 6.1 intake manifold and exhaust manifolds, or would/could all of the existing 5.7 induction and exhaust components be swapped over, including injectors, etc?

Kind of hijacking the thread a bit, but I am starting to plan the outcome of my 2016, as it will have over 200k in the next 3-4 years. Could a truck 6.4, or car 6.4 (bottom end and cylinder heads) be swapped into one of those with the stock 5.7 tune, using all of the 5.7 induction and exhaust components in order to pass CA visual examination? Of course, I would be beefing up the 65RFE trans as well.
