screaminchief, I AM on topic.
My EXPERIENCE with looking over stock blocks has reached a conclusion: good luck with thaat.
We balance the CYL wall thickness uniformity with Main Web integrity, and ADD the Cam bearing bore concentricity. If you remain tired of my advice then go-head, learn the hard way.
To DEVELOP this TOPIC:
(A) I have not yet seen a 425A block webbing pictured (well I could have missed it).
(B) 3 Steel Main Caps remain the key Stock block upgrade. How a fell goes about bolting them can be fine or ruinous.
(C) no bean left to spill. My opinion is you could start a block selection with an eye on superior Mains meat, then fail it on CYL core-shift or Cam tunnel bind. Says to me I've been lucky on block selection.
