If you’re going to bore the block before honing have them register the bores off of crankshaft thrust surface. If block will be filled give it time to cure before machining. Don’t forget to check the back of the block to be 90* to crankshaft center line. Also check your trans pump housing bore or bellhousing bore for being on crank center line and perpendicular. That way if the car doesn’t perform as you think it should you can look elsewhere. You know the cylinders are located, straight, round, and perpendicular to the crankshaft.

Sometimes straight, round, and perpendicular takes a while but I think worth the effort. Do what you can, within the rules, to keep the block from twisting.

Just some early morning thoughts.
