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 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?
The pistons included in the RB32 Stroker Kit have a compression ratio of 9.0:1. If you require a different compression ratio, custom pistons can be made for an additional fee and a lead time of 6-8 weeks.
Is line boring necessary after installing the RB32 crankshaft and connecting rods?
Line boring is not typically required for the RB32 crankshaft and connecting rods if the OEM main caps are used and installed correctly. However, it is advised to check alignment and clearances to ensure optimal performance.
Can I use the standard OEM crank girdle with 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.
