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?

What is the recommended bore clearance for the CP pistons in the RB32 Stroker Kit?
The recommended bore clearance for the CP pistons is typically around 0.0020" to 0.0025". However, this can vary based on your specific engine build and intended use, so it's essential to consult with your engine builder for the best results.
What is the compression ratio of the pistons included in the RB32 Stroker Kit?

Yes, the standard OEM crank girdle can be used with the RB32 crank setup. Ensure that it is in good condition and properly fitted to maintain engine stability.
