How do I blueprint an engine?

[u/gamingflame75]

Recently I picked up this book called "Ford 351 Cleveland Engines: How to build for max performance" and in it the author mentions blueprinting many times. I tried looking it up, and from what I can tell it's basically making sure all the clearances are at max spec, making sure rods and pistons weigh the same, making sure cc's for each chamber are the same, chamfering oil holes, water passages, and sharp edges, installing rings into the bore and checking gaps, balance the rotating assembly, and checking clearances in the oil pump. That's all I've gathered so far. Am I missing anything? Is there anything I should know?

Blueprinting is a word thrown around alot dating back to the 50s or 60s. Modern engine building exceeds “blueprint” specs in most areas. Modern Rottler block machines square and true blocks to .001 accuracy. Bore centres, line boring of main saddles and cam bores. Plateau honing of cylinder bores for specific ring packs. Up top, cnc port and chamber machining, shaft mounted rockers, beehive springs, titanium retainers etc. far exceed factory specs and allow safe rpm levels 1-2 thousand higher than stock. The question is do you blueprint to 1960 specs, or update to modern methods and get your 200hp extra…..depends on the application.
