Description

250-A 

262°/252° | 9.50mm/9.00mm

High performance aftermarket camshaft is designed for mild track day or street applications. Use with Ford Mustang Ecoboost near stock 2.3L engines. It is suitable for a 48-64mm turbo that produces up to 650hp. To use this camshaft, you will need to upgrade your valve springs.

Kelford Cams recommends the KVS250X-T valve spring and retainer kit.

Note:

  • Before installation you must check valve to piston clearance to ensure proper fit.

 

250-B

268°/278° | 10.50mm/10.50mm

Ultimate race performance to suit well-built Mustang Ecoboost 2.3L engines making 700hp+. Suits 64-72mm turbos with high RPM and big boost in mind. Valve spring upgrade required, Kelford Cams recommends KVS250X-T valve spring and retainer kit. Valve to piston clearance must be checked.

 

250-EZ

250°/248° | 8.00mm/7.50mm

Installing our Ford Mustang Ecoboost EZ Camshafts are designed to be a drop in on stock valve springs and original engine components. Customers looking to produce 320hp or more will experience outstanding performance when pairing it with a turbo upgrade.

When purchasing for an older engine that has high mileage we recommend Kelford Cams KVS250X-T valve spring kit to ensure optimal results.
