What is included in a typical Spool engine kit?
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 torque specifications for the ARP2000 bolts in the Spool Drag Pro I Beam conrods?
For the Spool Drag Pro I Beam conrods featuring ARP2000 7/16 bolts, the recommended torque specification is around 75 ft-lb when using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate guidance.
What machining considerations should I keep in mind when using the CP pistons in this rebuild kit?
When using the CP pistons, ensure that you set the correct bore clearance and ring gaps according to your engine's specifications. This is crucial for optimal performance and longevity. The pistons are designed for an 86.5mm bore, so verify your cylinder dimensions before installation.
Do the Spool Drag Pro I Beam conrods require any specific machining before installation?
Yes, the big-end or small-end of the Spool Drag Pro I Beam conrods may require honing to ensure a proper fit due to factory journal and pin size variations. It's essential to check clearances and perform any necessary machining for reliable operation.
What type of head gasket is included in the rebuild kit and what are the surface finish requirements?
The rebuild kit includes a Cometic MLS head gasket. For optimal sealing, ensure that the cylinder head and block surfaces have the correct RA surface finish as specified by the gasket manufacturer. This will help prevent leaks and ensure a proper seal under high pressure.
What is the compression ratio of the CP pistons included in this kit, and how does it affect performance?
The CP pistons in this kit have a compression ratio of 9.0:1. This ratio is suitable for a balance of power and reliability, particularly in a performance application. However, final performance will depend on factors such as tuning, fuel quality, and boost levels.
