what does it mean to have your camshaft blueprinted? did a search didnt find anything on it other than blueprinted cams for sale/people showing off their builds

 

good question, wish i knew the answer.

in to read about it though

 

hmm think i foudn it, can anyone tell me if this is right?

"In engine blueprinting, all the specifications are double-checked. Usually this indicates closer-than-factory tolerances, with custom specifications appropriate for a street car or a race car. The goals usually are to:

Ensure the engine puts out the rated power (because not all mass-production engines put out the rated power) for its manufacturer's design
or

Make more power out of a given engine design, by extra careful measurement and assembly balancing of reciprocating parts and rotating assemblies, to reduce engine vibrations thus achieving more power due to recover of power "lost" to vibrations"

 

yeah Ive know what engine bluprinting is, but I have never heard of a blueprinted camshaft, I would imagine that someone just mic'd all the lobes to make sure they were the right height and placement/centerline....
