Not a Hemi but a 3.6 V6

That's great and I'm happy for you. Unfortunately some of us don't have access to the tools you do, so we're stuck paying for it. Any idea on how wide this 3.6 is? I have a '64 Valiant and I'm really considering this swap down the road. I've read the engine compartment is around 2 inches narrower then the '67 up body. Where did you get your engine from?

Well you only need the $1200 QuickTime bell housing if you chose to use a +$2000 TKO 5 speed.

I've done tons of R&D on swaping a 3.6L and have listed several transmission options in my build thread:
72 Dart Swinger 3.6L Pentastar +T5

My 3.6L came out of a 2013 Wrangler.
