Help with decking or not?

Most guys who want things "perfect" would cringe if they actually knew how far off a "balance" job can be without any real world consequences.

While we tend to expect to see or hear a difference most engines will happily run hundreds of thousands of miles without any issues with an inbalance that would drive some folks crazy if they only knew.

Yes and if those same guys wanting perfection knew how far off everything was from the factory and how many millions of miles engines racked up in all makes and models, they would fall out.

That said, there's nothing wrong with blueprinting everything to where it "should be". Makes the engine more accurate all the way up.
