Here is a maximum-effort piston and rod assembly. What we see here is a Lunati piston with a diamond-like coating on a lightweight pin along with thermal barrier and anti-friction coatings on the rest of the piston. This lightweight Lunati 6-inch Sprint car rod has an oil-shedding Teflon coating. All this was good for an 8,000-rpm redline in a 441-inch, street-driven, small-block Chevy.
