On Passon's 5 speed, do you know what that brass plug is on the top driver side of the trans is? Assuming the fill plug is that bigger plug in the middle of the passenger side main case...

So if the switch is laying on a forty degree workbench it should be closed I would guess, right?

What fit issues did you come across, putting a gen 3 hemi in your barracuda? Was thinking of doing the same, because I came across a good deal on gen 3 hemi from a dealership. Currently I am building a 67 fastback barracuda. Just ordered a new k member from HDK, got to make up my mind quick,because I was originally going to use a 440.
