Watch the video and see how GM hones the block with torque plates for the new 580 horsepower ZL-1 Camaro.The 6.2 liter supercharged V-8 is among the most powerful GM has offered in a street legal drive it off the lot vehicle.
As the video explains honing a block with torque plates simulates a head being bolted on and the honing operation will be more accurate as the cylinders will be just as they are with the motor assembled.When the heads are bolted on and torqued down it slightly distorts the cylinder bores of the block.Honing the block with torque plates will keep the bores stressed while the honing operation is done.This ensures a rounder bore and better ring seal which means more horsepower and torque.
This process is something you would normally see in a performance or racing engine application but not commonly in a production car.
It is a great idea for the supercharged 6.2 ZL-1 though as it is not your typical Grandma's ride.

Powering the 2013 Ford Shelby GT500 is a 5.8-liter supercharged V8
that generates an awe-inspiring 662 hp and 631 pound-feet of torque.
Just as impressive as the peak output is the fact that 395 lb-ft of that
torque is available just off idle. A six-speed manual is the only
transmission available.
Despite the lofty power output and performance figures, the EPA
estimates fuel economy at a fairly reasonable 15 mpg city/24 mpg highway
and 18 mpg in combined driving.
With a base price around $55,000 it is a true 200 mph hot rod that won't break the bank - at least compared to some of the exotics.
Also available in a convertible with a power operated soft top.
