He's still doing them. I pick mine up on Friday.
He is quite busy, and this is a side hustle for him.
Patience is the key here. Solid dude, and he will respond, but at his pace/schedule, not yours. If you can't handle that when he's got your rig, I'd advise against. If you want a great VK swap, consider it a lesson in patience. It's done when it's done right, not right now.
I engaged him in Feb. '22, deposit in March so he could start collecting donor engine/trans//parts, dropped it off in August (I'm from WA) when my work allowed. Got the video of it starting and new, blue dash lights yesterday. I fly out Friday for Cincinnati.
