Oops, does a 6.760 rod sound right? I see Best Machine selling crate motors with this same rotating assembly.

440 source will knock off $150 w/o the balance job. So it would be $1747. Mancini's kit looks better to me at $1450. 440 source has a 4.15 stroke kit but it uses a Mopar Rod journal. I thought the BBC journal was the way to go these days.
