Kits usually include pistons, rings, rods, bearings and related hardware depending on the engine family. Check the listing for exact inclusions.
Do I still need machining with a full engine kit?
Yes. The block must be honed and all clearances checked and set by your builder. Assembly should only occur after full measurement and verification.
What are the recommended bore clearance and ring gap settings for the CP pistons in the Ford EB/ED/EL/EF engine?
Bore clearance and ring gap settings for the CP pistons should be determined by the engine builder based on the specific application and intended use. Typically, a clearance of 0.0015" to 0.0020" is common for performance applications, but always refer to the manufacturer's guidelines and adjust based on your engine's operating conditions.
What is the torque specification for the ARP2000 bolts used in the Spool conrods?
The ARP2000 bolts in the Spool conrods should be torqued to approximately 55 ft-lb when using ARP Ultra-Torque lubricant. Always ensure to follow ARP’s latest instructions for the most accurate specifications.
Can I use these conrods and pistons for a high boost application in my Ford 4.0L inline 6?
Yes, the Spool H Beam conrods and custom CP pistons are designed to handle performance applications, including high boost setups. However, reliability will depend on proper machining, clearances, tuning, fuel quality, and boost levels. Ensure your engine is built to withstand the stresses of increased power.
What is the lead time for the custom CP pistons when ordering with the Spool conrods?
The custom CP pistons typically have a turnaround time of around 18 weeks from the date of order. This allows for precise manufacturing to meet your specific bore size and compression ratio requirements.
Are there any specific machining requirements for the Spool conrods when installing them in the Ford EB/ED/EL/EF engine?
Yes, the Spool conrods may require big-end or small-end honing to ensure proper fitment due to factory journal and pin size variations. It's crucial to check clearances and ensure the rods are correctly aligned during installation.
