Description
Street Performance. This Ford Racing cam is a excellent replacement choice for good low-end torque, a significant increase in top-end power above 4,000 RPM, and a fair Idle.

Legendary Ford Racing Quality. When you're adding performance parts to your Pony, you can't go wrong by installing parts from the folks that know it best. Ford Racing's legendary quality ensures a perfect fit and years of hassle-free use.

Required Upgrade. This Ford Racing B303 Performance Camshaft requires upgraded valve springs for proper operation. Valve spring requirements: 120 lbs valve seat pressure minimum 295 lbs open. For stock cylinder head applications, the use of Ford Racing M-6513-A50 valve springs installed at 1.820" are recommended.

Application. The Ford Racing B303 Performance Camshaft is designed for use in the 1985-1995 5.0L V8 Mustangs with a roller cam block and 1.60 rockers.

LOVE IT!

I had this cam installed in my 1988 Mustang GT. As a daily driver I didn't want a cam that was too big. So I opt'd for the B303 and couldn't be happier. Sounds Great!

will the b303 cam work with stock heads? if not wat heads and cam combo do you recommend?

95gt Year: 1995 Model: GT

  • Will work with stock heads but a better flowing head would be ideal, or you can port the stock heads and put better springs and retainers.

    Great Cam, can't go wrong with Ford Racing

    The cam itself didn't take all that long because the engine was on a stand getting rebuilt. If it was done in the car i would think it would take significantly longer. The fit was good and it has a great idle and power band.

    b303 camshaft

    The cam went in very easily. Sounds awesome. Sounds very CHOPPY. Gets alot of compliments from others on the way it sounds. Great cam for power increase on a stock 5.0.

    B303 is the best inexpensive cam for stock bottom end!

    I build ford engines for a living and I personally think the FRPP B303 SBF camshaft is the best bang for the buck, performance improvement is my favorite for the stock 87-95 Mustang 5.0 pistons.

    Very Lumpy

    This cam is great for street rods. It has a very lumpy idle and a great overall sound. It also has a nice performance gain. I would definitely recommend this cam. It is 10x better than a stock cam.
