FAQ
Is this a direct stock replacement?
Yes. This short block is built to OE specifications and is intended to restore factory performance and reliability when paired with stock components.
What parts come pre-installed?
The block, crankshaft, connecting rods, pistons, rings, bearings, and freeze plugs are installed. External components (head, front cover, oiling system, timing, fuel/turbo) are transferred from your engine.
Does this short block include a camshaft?
No. Reuse your camshaft or add a new/reconditioned cam during assembly if required.
Do I need tuning after install?
For a stock replacement using factory hardware and emissions equipment, no additional tuning is needed beyond factory calibration.
What break-in procedure do you recommend?
Prime the oil system, use conventional oil for initial break-in, vary load and RPM (avoid extended idling), and change oil & filter early. Follow shop best practices.
Is there a core charge or freight policy?
Core and freight options may apply depending on your location and selection. Please review CPP’s current policies at checkout or contact us for a quote.
