Nice info...........

Do they do this on the CTS-V LSA too?

Yes. Common process with ZR1, Z06 and CTSV and Camaro ZL1 blocks.

Is there an echo in here?

Cool and all but probably not necessary for 99.99% of us who use our cars as daily drivers.

Basically in short, this is them breaking in the engine correct? This process helps seat the rings?

LMAO

For a reliable engine over extended years? it would relate to all of us..

However, what I don't get is it says a near perfect design based on this honing...so if that near perfect..what in the world is in our cars? Just decent? Not trying to sound whiny, just have no knowledge of this process.

Interesting, dont really know what this means but interesting lol
so will it have more hp? lol

Deck plate honing nearly duplicates the head bolt loads that cause distortion in the block when they are screwed in. By using the same gaskets, bolts, and torquing procedure, the cylinders deform like they would after the engine is assembled. After the plate is on, honing the cylinders makes them perfectly round again thereby eliminating blow-by and keeping the cylinder shape constant, improving efficiency and getting a longer life. When the engine runs, the block actually twists and deforms, and gets pulled every which way when all the components are screwed and bolted to it. By duplicating the loads that influence the distortion, you eliminate little inconsistancies, get a happier engine that will live a longer life. This is more important when pushing a design to it's limits. The higher the performance, the less room there is for error. This process is one that racers have been using for ions, and while these little inconsistancies don't effect the engine too much, when you're looking for every little bit of power, or looking for hitting a specific safety factor when you're pushing the envelop, this is one of the tools one can use to nearly assure the best running and longest lasting engine possible. If you've ever heard of engine blue-printing - this is an element of that process.

When I had the LT-1 engine built for my '73 Corvette in 1975 the engine builder used a torque plate, and a few years later the engine was checked by a local guy who ran Top Fuel dragsters and he told me my engine had better leak-down than his mega-buck Top Fuel engines. I definitely think it's worth it.

WOW! That is really something! AND it makes so much sense. I've been a licensed mechanic for 28 years and knew nothing of this process. Mind you, I've never been into building high performance engines, but I'm glad I learned about this process.

Can never be too information savvy! LOL

Wouldn't you think this process would be used on all the engines for a better product?

It cost factor that probably preventing them from doing that, and extra time.
