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 bore clearances for the Ross forged pistons in this rebuild kit?
The recommended bore clearance for the Ross forged pistons typically ranges from 0.0015" to 0.0025" depending on the application and operating conditions. It's crucial to consult with your engine builder to determine the best clearance for your specific setup.
What compression ratio options are available with the Ross pistons in this kit?
This rebuild kit offers Ross pistons with compression ratios of 8.5:1 and 9:1. The choice of compression ratio will depend on your intended use, fuel quality, and tuning strategy.
What are the torque specifications for the ARP2000 bolts included with the Spool conrods?
The ARP2000 bolts included with the Spool H Beam conrods should be torqued to approximately 55 ft-lb when using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate specifications.
Do the conrods require any specific machining before installation?
Yes, the Spool H Beam conrods may require big-end or small-end honing to ensure proper fitment due to factory journal and pin size variations. It's essential to check clearances and perform any necessary machining before installation.
What type of head gasket is included in this rebuild kit?
The rebuild kit includes a Cometic MLS (Multi-Layer Steel) head gasket, which is designed for high-performance applications. Ensure that the cylinder head and block surfaces have the correct RA surface finish for optimal sealing.
