Long block Mopar 6.4 - What's included/missing?

Something you may not have considered:
As noted above, you'll need a front cover, and you want the "old school" look-
Have you considered using Arrington Performance's distributor conversion and front cover on the long block? Youll need to buy a cover anyway. Cuts down on the necessary sensor, harness and computer costs and issues, too.

Just a thought.

Yeah I saw that but would rather keep fuel injection. I installed the Sniper and Fitech on my dad's 71 Hemi GTX and 72 440 Cuda, respectively. My old school look really is just the intake, possibly relocating the coil packs, and painting it all orange with black valve covers.
