Everything is balanced, weighed, polished, and makes for a LOT smoother bottom end.

And matched in size /dimensions / tolerances. Aims to fit better.

generally will get some extra power and hopefully reliability out of it.

ahh Ok thanks, i was unsure as to exactly what this meant, i thought it was sumthing like that tho.

Blueprinting is just that, making an engine exactly like the blueprint, with much better tolerances than the typical production line.

CC'ing combustion chambers so they are all exactly the same, making sure bearing clearances are all perfect, ring gaps, piston clearances, etc, etc.

And engine will be typically be smoother and run more efficient when blueprinted, and it is mainly required if it's in a high state of tune.
A standard engine will likely not benefit much (if at all) from blueprinting.

YOOT

HSV had this option with the stroked 5.0L V8 (5.7L) in the VR/VS Senator and GTS. It was a $10,000 option but yielded a 30kw or so increase in power to an already impressive understated 230kw motor.

Supposedly these blueprinted mills where absolute gems!! Much better than any Gen 3 today, so I've heard.

so what does blueprinting cost on say a 4.0L when doing a rebuild?
