The iron in that stovebolt block could probably be recast into 3 or 4 modern 4 cylinder engines. I doubt that you'll be able to notice any difference in cylinder roundness whether a 235 is honed with a torque plate or not. If you're really concerned about it, torque a junk cylinder head onto the block and hone the cylinders from the bottom side. I'd love to hide and watch that procedure!

Fair point. There’s a bit of heft to a 235 casting.
My son and I have been piddling with a 5.0 F0rd lately (I tried to raise him better). I’m amazed how easily a guy can move around a bare 5.0 block.
