Atomic Barra 1000hp Capable Parts Package
Engineering Overview
SPEC-DOC
Atomic 1000HP Engine Package
Uncompromising Engineering
The core philosophy of Atomic is uncompromising engineering. Every feature of this kit is designed to ensure maximum component longevity and reliability under extreme race conditions.
We use H13 Tool Steel for our Head Studs. Most kits use ARP2000, but our H13 Tool Steel studs offer superior tensile strength, ensuring the head stays clamped down even under the immense cylinder pressures of a 1000HP setup.
Zero Failure History
Our connecting rods are best-in-class with a 20-year history of zero failures. We combine this with pressure-fed pin oiling to ensure your bottom end survives the abuse of 4-digit horsepower.
What's In The Box?
