Description
Street/Strip Performance. This Ford Racing cam is a great replacement choice for increasing your pony's torque and horsepower up to 6200 RPM, and it has a fair idle.

Application. The Ford Racing X303 Performance Camshaft is designed for use in the 1985-1995 5.0L V8 Mustangs with 1.60 rockers.

Technical Notes. Ford Racing recommends the use of a Hi-Stall torque converter for Mustangs equipped with automatic transmissions. Valve clearance should be checked, as it may require piston modification for piston-to-valve clearance.

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.

can i replace stock cam with this one and still use my rockersand lifters Can i use this cam in place of stock one and still use my rockers and roller lifters

  • Yes, you can use this cam with roller lifters and stock rocker arms but you will have to use stiifer valve springs than the stock ones. The higher lift of a performance cam puts more pressure on the springs, therefore a stiffer spring will be required.

    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)
