Rebuilding a 2008/2010 engine

Bad news. The 2008 and 2010 are to very diffrent motors in 2009 the Hemi changed to variable timing. And 2008 and 2010 heads are diffrent the cam is diffrent the accessories are diffrent, timing chain covers are diffrent, you can physically bolt the 2008 heads on but that where it ends the ports, and combustion chambers are completely diffrent. You need to find 03-08 stuff or keep the 2010 block and find everything else that's 2009-2012. You can make the 08 heads work but it will take alot of reworking, but none of the other stuff will work. It's all up to you.

Actually alot will work. they are very much the same motor. the 2010 heads arn't all that different from the 2008 heads bigger ports, combustion chambers are basically identical. honestly other then a slightly different air flow I could probably have my heads decked and they'd work like the 09+

The 2010 block had mounting bosses for the VVT timing components that the 08 doesn't. and the water temperature plug goes out the back of the block instead of the front like the 08. minor differences

I had the 2010 all assembled but I stripped it apart to inspect and clean the components.

Also anyone know heir theirs a special deep socket for the one main bolt that supports the windage tray?it's goofy long with a bulb kinda shape at the end that my deep ssockets won't fit over.
