Which manifolds? 2014 5.7

I just bought a 2014 5.7 out of a Ram 1500 :blob: and am hoping you guys can help me pick which exhaust manifolds or inexpensive headers to use.

I have been reading the Hemi swap posts until my eyes are crossed but am not sure which exhaust manifolds will work. The driver side factory manifold looks like it would have to go through the firewall to work. I believe I read somewhere that the exhaust manifolds on 2009 and up are different than 2003-08.

The plan is to put this into a 67 or 71 Dart.
I have a flaming river manual steering box to install at some point. Not sure if this allows more clearance than a stock manual box.

I have two k frames to choose from.
73 up slant and 73 up v8.

I believe the TTi mounts are the motor mounts I will use unless someone has some ideas to share on what else to use.

Any advice is appreciated.

Mike
