Fully machined, heat treated, stress relieved, shot peened, and 100% individually magnafluxed — every rod gets inspected, not a sample from the batch.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThe finishing is what separates a Manley H-beam from a cheap one. Big and small end bores are final honed to ±.0002\", bend and twist are held to a minimum, and sets are weight matched to ±1.5 grams. Bushed small end for a full-floating wrist pin.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eRated to 600 hp\u003c\/strong\u003e with the right supporting hardware. That covers most built EJ setups — a stock-block replacement on a boosted street car, or the foundation of a proper build.
