FAQ

Q: Will this short block handle towing with mild upgrades?
A: Yes. It’s built as a strong foundation for towing and performance. Pair it with quality injectors, a healthy CP3, and proper cooling, and you’re set.

Q: Do I need a new cylinder head?
A: Not required, but highly recommended if your original head has cracks or poor sealing. See our 03–07 head options.

Q: Is a CP3 upgrade necessary?
A: For stock or near-stock power, your CP3 may be fine. For larger injectors/turbo, step up to the S&S CP3 for stable rail pressure.
