Click to expand...

The F303 cam has a 0.050" lift duration of 226* (advertised 288*), lobe separation angle of 114* (good blower cam), intake centerline of 109*, and a valve lift of 0.512" with 1.6 ratio rockers.
You'll need to check the PTV clearance and upgrade the valve springs on the Cobra heads. Should be OK without a tune but not ideal.
