I know this may seem silly to ask, but can someone give me an explanation of balancing & blueprinting and engine. I have an LT1 block that I plan to make (hopefully) 400+ rwhp 355.

Thanks for helping a new post guy.

 

It's basically exactly what it says. The rotating assembly is "balanced" and then the engine is assembled to the manufacturer's exact specs (or blueprint). It can give you some extra HP since everything will be exactly matched to the design specs, but the main benefit is in exteneded lifespan.

 

Here's a link with an example of what is done:

Thanks for the info and the link. I'll read it over carefully.
By the way nice z06 & firehawk.

 

Well, ya, the mfr. engineering blueprint specs are used as a benchmark/basis for the assembly and machining process, but I prefer to explain it as stating that the engine is assembled putting the specs, which, being important, include the tolerances, in the more advantageous 'zone' of the tolerance range. IOW, some specs are more appropriately put in the 'plus' zone/side of the tolerance range, some are put in the 'minus' side of the range. It depends. But ya, you use the engineering specs as a basis to start with. As far as the link above is concerned, a little misleading, AFAIC. Be careful, as to how much weight is put on what you read, internet web sites or car rags. Actually, ESPECIALLY, web sites.
