I've seen some Mopar stock BB.B and 426 Hemi blocks that I have sonic tested have .350 on side an .0120 on the other shock
Most of the early street hemi blocks are decent, some are excellent up But most of those are taken now whiney
I built one new Hemi Mega block that was rough bored to 4.180 and it wasn't thick enough for me to go above 4.250 final bore with a Roots 10:71 on pump swill, we increase the stroke to 4.375 instead of going to 4.310 bore or bigger shruggy
That motor made 927 HP at 7300 RPM on CA pump swill with 7.5 lbs. of boost boogie
The owners chassis wouldn't hook 700 HP, let alone 900+ HP whiney It was a real tire spinner whiney
