Good To Know

Q: Is this kit complete for a top end rebuild? A: Yes, it includes pistons, rings, wrist pins, and circlips; you will still need gaskets and seals.

Q: What compression ratio will I get with this .020 over bore? A: The compression ratio is slightly increased due to the larger bore, but it remains suitable for stock fuel mapping.
