I am not commenting on the level of QC between a standard 360
and a Challenge Stradale.
What I said was the level of manual labour it takes to convert a
standard 360 to a CS spec.
This is similar to the work that goes on in a Type R engine, which
takes a factory finished engine and then uses painstaking manual
labour to make it into a true Type R engine. Let's not belittle
this process.
Look at this link.

The Integra's VTEC B18C type engine retained its stock
displacement, but Honda increased its horsepower from 180 to 200.
It's only *20* horses more, but those 20 horses were really tweaked
out using Honda's formula 1 knowledge -- from an engine that was
already getting 100 horsepower per liter. Fumiyasu Suga, Type R's
assistant chief engineer, was kind enough to sit down with
us.
Currently, production line engines and engine parts are
made by computer-guided NCR machines, and are of very high
quality. However, Mr. Suga believes that in order to make a
true race engine, some parts must be
built/assembled by hand. In specific, the
assembling of the engine, balancing parts, and porting and
polishing need to be done by hand. Amazingly, all Type R engines
are built this way.
