My father passed away shortly after having this motor assembled in July of 2020. It's sealed up and tucked away under an engine bag, sitting on the oil pan rails on a wooden transport jig I made. The motor has never been run, all parts are brand new and never used / broken in. I don't know a ton about it, other than what the engine builder said.
Here is all the info I do have. A lot of part numbers and some background info from the shop (when I called they said they didn't keep a lot of records on it). If you look through my posts, you'll see I've been asking about this and researching since my dad passed. I'm trying to fund a build so I can get his Dart on the road again. I'm going the BB route too to honor his vision, but figured this would be too much to put on the street for me. From what I've gathered, it'd need appx. 4k stall and that's just too much for me.
If any well-reputed members can vouch for the shop or builder (if they know of them) I'd be extremely appreciative.
