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 compression ratios can I choose for the CP forged pistons in the Ford AU 4.0L rebuild kit?
The CP forged pistons in this rebuild kit are custom made, allowing you to specify any compression ratio that suits your build. It's essential to consider your engine's intended use and tuning when selecting the compression ratio.
What type of fasteners are used in the Spool H Beam conrods, and can I upgrade them?
The Spool H Beam conrods come standard with ARP2000 fasteners. If you're looking for increased strength, you can opt for an upgrade to L19 fasteners, which provide enhanced performance under high-stress conditions.
What are the recommended machining requirements for the CP pistons?
When using CP pistons, it's crucial to set the correct bore clearance and ring gaps according to your engine's specifications. This ensures optimal performance and reliability. Always consult with your engine builder for precise measurements.
How long will it take to receive the CP forged pistons after placing an order?
Once ordered, the CP forged pistons typically take around 6 to 8 weeks to manufacture and deliver. Plan your build timeline accordingly to accommodate this lead time.
What is the significance of the Cometic MLS head gasket included in the kit?
The Cometic MLS head gasket is designed for high-performance applications, providing excellent sealing capabilities under high pressure and temperature conditions. Ensure that the cylinder head and block surfaces have the correct RA surface finish for optimal gasket performance.
