Tom,
In my specific case I have the following; A .030" over 400 block, obviously a 3" crank journal, Very light rods(700g), pistons are 543g, so my bob weight is 2003g. I'm figuring this engine can live many years on the STREET occasionally hitting 6000rpm using the King MB5526AM and CR815CP bearings.
