Hey Guys, I have a 2010 Chevrolet Tahoe PPV with a 5.3L LMG and a 6L80 Trans (MYC) looking to drop in a 6.2L L9H. As far as I understand it is a direct swap. Would I run in to any issues or codes as far as the L9H not having AFM/DOD? I plan on using the 5.3L PCM and having it re flashed to work with the 6.2 Or do I look for a L94 that has FlexFuel, VVT, AFM like the LMG does?
2008 Silverado 5.3 LMG has a knock at 160k miles. I have decided to go the route of a Goodwrench remanufactured long block. It says that it includes oil pan, timing cover, harmonic balancer and gasket kit. I will swap over all the main parts from the old engine intake manifold, valve covers, accessories, etc. What I am not sure about are sensors (knock sensors, coolant temp sensors, etc.), which sensors can I transfer to the new engine and which should be replaced? Any other parts you might suggest replacing would be appreciated, I don't want to be stopped in the middle of the job because we forgot a part.
