My non Mopar project last summer. I put a 5.3 L83 on an airboat. Studied putting a gen3 on one but there's almost zero aftermarket support for it in the airboat industry. Didn't feel like going to the extra trouble. Mines straight out of a 2015 Silverado. It's an LT, no more LS designation. It's a freakin beast for 325 ci. Easy peazy to do, too.
