Hey David,
Another thought on the high revving small block. In my experience, revs on pushrod engines have always been limited by valve train more so than the bottom end. How does your next door guy deal with that?
As far as align honing is concerned, it is usually performed to round out mains that have been beaten out of round. The object is to align the bore with the journals on the crank so that you don't have any high spots in the crankshaft and bearing contact faces. If you look at the main caps on a high performance engine, you'll notice that after time, the caps tend to deform along the cylinder axis, where the piston was at the bottom of it's travel. Makes sense right?
