Frequently Asked Questions

What's included in the Power Package?

4.32" cylinders, matched cam, cam plate, oil pump, and all cam chest components needed for a complete build.

Do I need to port and polish the heads?

The cylinders are precision-machined, but head work is a separate decision based on your performance goals and budget.

Will this fit my Harley?

This kit fits Harley-Davidson models. Confirm your specific year and engine type with S&S or your engine builder for final compatibility.

Do I need a tuner with this kit?

Yes — a complete big-bore build typically requires ECM tuning or carburetor rejetting to maximize power and drivability.

Is this a complete engine or a top-end kit?

This is a camshaft and induction system package. You will still need your original crankcase, cases, and bottom-end components.
