Helpful Notes
- 60% over injectors are best paired with adequate low-pressure fuel supply and appropriate tuning.
- Always use clean fuel and follow proper priming procedures after injector service.
Most 60% over builds benefit from tuning to optimize fuel quantity, timing, and emissions strategies. Consult your tuner for your exact combo.
Is a core return required?
Yes. A core return is required on 6.4L Ford injectors. Orders without core return are subject to a core charge.
What’s the difference between SAC and VCO nozzles?
SAC (sac-type) nozzles typically support higher flow and durability for performance builds. S&S uses precise honing and matching to maintain clean combustion.
Can I daily drive with 60% over injectors?
Yes, with proper supporting mods and tuning. Expect more fuel delivery capacity; match turbo, pump, and tuning accordingly for smoke control and EGT management.
