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 clearances for the CP Bullet pistons in this rebuild kit?
For CP Bullet pistons, a typical bore clearance of 0.0030" to 0.0035" is recommended. Ring gaps should be set according to the intended use, generally around 0.020" for naturally aspirated applications and up to 0.030" for boosted applications. Always confirm with your engine builder for specific requirements.
What torque specifications should I use for the ARP 2000 bolts on the Spool conrods?
For the 7/16" ARP 2000 bolts included in this kit, the recommended torque is approximately 75 ft-lb when using ARP Ultra-Torque lubricant. Ensure to follow ARP's latest instructions for the most accurate specifications.
Do I need to modify my engine block to fit the Spool conrods?
Clearancing of the cylinder block may be required when using Spool conrods, especially if you are increasing stroke or using larger pistons. It's crucial to check for adequate clearance during the build process to avoid any interference.
What type of bearings are included in the LS rebuild kit and what are their specifications?
The kit includes ACL Race Series big-end and main bearings, designed for high-performance applications. Ensure that the bearing clearances are set according to your engine's specifications and intended power levels.
Can I upgrade the conrods in this kit to L19 bolts, and what is the installation process?
Yes, you can upgrade to L19 bolts for the Spool conrods. When using L19 bolts, they should be tightened by measuring stretch rather than torque, aiming for a stretch of 0.0070" to 0.0074" for 7/16" bolts. Always refer to ARP's guidelines for the most accurate installation practices.
