    I have a 88 GT with 89 engine.i was told by the seller that it had a stock lower end and cast victor senior heads. Idle brac intake and 65 millimeter throttlebody with 24 lb injectors.I am looking for good strong cam that will come in from 1500 and be strong pulling up to 6000.The heads have 202 with 160 valves.What would recommend.Thank’s


    • The Ford Performance X303 Performance Camshaft may not be the best cam for your setup, however we would need more information, such as the cylinder head part number to determine intake and exhaust runner volume, combustion chamber size, etc. We would also need to know the specific intake manifold, and if the car is automatic or manual, and if automatic, the stall speed of your torque converter. Please contact our customer service department so that we may best assist you with this.

    What length pushrods do I need ? My stock rockers and pushrods are not working.


    • With the Ford Performance X303 Performance Camshaft, pushrod length should be measured, as depending on production tolerances, required length will vary.

    I have a mustang 1986 original fuel injection do I have to make any modifications for this camshaft?


    • You will not need to do any modifications for this camshaft no! Now it is recommended to check for valve clearance but this should not be an issue with the X cam.

      Nice but just when you have the right set up

      I have a 351w and it is a roller cam ... the only way to do is to make to swap of the flat tappet lifter to the roller lifter (need the lifter the spyder and the holder of a 302). If you are looking for this cam be sure to have a realy mod engine (more than 400 hp)

      Pretty good for the money.

      The cam is calm and streetable until 4000 RPM and then its like a supercharger kicks in. Just wish some of the power could be harnest a bit earlier.

      X303 is a great value

      a good performance cam with a fairly lopey idle, even with the stock efi eecIV. makes about 15inches of vacuum at idle. may require IAC plate to help adjust idle. great sounding cam with a lot of topend power. don't forget to install new lifters with the correct length pushrods.

      I am rebuilding my 302 and decided to go with the X303 cam. Since I am still puttingt he engine together I don't know how much power gain I have yet. I can't wait to fire it up and see hows he does.
