Mopar R1 block

I haven’t seen it yet. Only spoke with him twice about it.
Extremely knowledgeable person he is!
From what I understand it’s a 59 deg block, with 2 bolt mains, 340 main size, cast in the engine mounts, rough bored never run, standard deck height, so my intake and heads should work W5 and M1 small runner single plane intake with the spacer.
The wife has so far been receptive about it.
I’m wrapping up a near total restoration of her 440 six pack Challenger, so that helps, plus she remembers what I said about replacing the TA engine I sold, one day. Well it’s here.
I appreciate all the info guys, so I should pull some measurements when I see it, and the numbers, and if it checks out drop the cash. It’s a fraction of what I sold the TA engine for, and I’ll focus on some main caps, and let my machinist have it, and tell me what bore size is safe. He errors on the safe side. I’m getting excited!
