Hi Guys, just signed up on the site yesterday after reading through a few hundred posts. i have a question regarding the L9H, but a swap. if it needs to be moved, i can do so. I currently have a 2009 GMC Sierra 1500 CC z71 w/ the 5.3 & the 6 speed. i'm looking to swap order a new GM crate L9H. from reading on here and a few other sites, i see that about 95% of the parts are transferrable between the 2 engines, the crate will come with all new internals (cam, crank, pistons, plugs, etc...) i wanted to confirm a few parts that i will need, hopefully someone else has done this on here and has the same list: - new intake manifold - new injectors - new fuel rails - possible new ecu (computer) are there any other parts that i might have overlooked or anything that i need to double check? any advice or pointers during & after the install would be great! best price so far that i've found is from Karl Performance Chevrolet in Iowa (https://www.karlperformanceparts.com/p/19210971-6-2L-Gen-IV-379-CID-GM-Engine/1761) i'm in california so there's no shipping charge or tax, that saves me about $750 right there! thanks for the help in advance Mike
