balance and blueprint?

balance and blueprint?
I don't see much discussion on this nowadays. Do most people buy parts and assemble them without any prep? When you order a rotating assembly, do these typically come B&B? And if so, what is the min industry standard for this in terms of tasks? Just curious what the standard is these days as I never read about these things in detail.

This is just an overview. Most people just have their rotating assembly balanced and throw it together and call it "balanced and blueprinted" though.

don't forget deburing the block, making sure every oil passage is clear for return, remove and smooth any cast marks, for some it is the only way to build a motor like a religion, for others it is just slap it to gather and run it like it is.

what about piston prep?

Piston prep
Yes normally in a hi-po build a machinist/assembler will check the piston ring grooves and as mentioned earlier, hand file-fitted(gapped).
I myself have a set of JE pistons that are new paperweights b/c the 3rd ring land is is 1/32" from the wrist pin.
I balance my motors for longevity/durability especially when they are not stock builds. and I will not trust any companies machining. The upper U.S. brands (Crower,Callies,Oliver,JE, Cunningham and others) are normally close and you get what you pay for in precision parts. Imports lack q.c. as I've seen rods be out .003-.005 out of round and new forged cranks needing turning .010.
Off my soapbox, and hoped that helped a little.
