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 Racing Pistons in this rebuild kit?
For the Ross Racing Pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended for optimal performance. However, exact clearances should be determined by the engine builder based on the specific application and intended use.
What is the proper torque specification for the ARP bolts included in the Spool H Beam Conrods?
The Spool H Beam Conrods come standard with ARP2000 bolts, which should be torqued to approximately 55 ft-lb using ARP Ultra-Torque lubricant for 3/8" bolts. If you opt for the L19 upgrade, follow the stretch method rather than torque, aiming for 0.0060"–0.0065".
Are the Cometic MLS head gaskets suitable for high boost applications?
Yes, the Cometic MLS head gaskets included in this kit are designed to handle high boost applications, making them suitable for turbocharged or supercharged setups. Ensure that the cylinder head and block surfaces have the correct RA finish for optimal sealing.
What is the significance of the -11.3cc dish volume in the Ross Pistons?
The -11.3cc dish volume in the Ross Pistons helps to reduce the compression ratio, which is beneficial for supercharged applications. This allows for better detonation resistance and tuning flexibility, especially when running higher boost levels.
Do I need to perform any specific machining on the conrods or pistons before installation?
Yes, the conrods may require big-end or small-end honing to ensure proper fitment due to variations in journal and pin sizes. Additionally, the pistons will need to be fitted with the correct bore clearance and ring gaps set by the engine builder for optimal performance.
