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.



That sounds better , but a longer rod would be better to make the piston package smaller and less rotating mass .

sounds like the eagle crank is using a mopar sized big end , the BBC big end provides more clearance .

As far as which is better , I'll spare the board from the abuse I'll get from the ..
