    Will a f-303 cam work with a stock intake on a 1987 mustang? I've got a 40 over flat top bottom end and a stock set of heads I'm wanting to know if the f-303 cam will work with those parts. I've got a guy wanting to sale a set of cobre gt 40 heads and intake with 1.70 roller rockers but if I don't have to have them then I would perfer to stick with what I have.


    • As with any camshaft, the Ford Performance F303 Performance Camshaft will need to be measured for proper piston-to-valve clearance. I would not recommend just dropping in camshafts, without checking clearances, even on a stock valve-train.

    If i was to install this in a stock block 302 from a 1986 GT, would I need to get a mass airflow meter and/or sensor?


    • In order to install in an 86 5.0L a MAF conversion would be required. Additionally piston to valve clearance will need to be checked due to the 86 having flat tops with no valve reliefs.

    I have a stock 95 5.0 motor, my foxbody has been converted to mass air. Can I use all my stock components with this cam? (rockers, springs, valves, hydraulic lifters) or do I need to upgrade anything on my motor to run this camshaft?


    • You would be able to use those components with this cam, it is designed for those engines with the use of the 1.6 ratio rockers, it is always recommended to check PTVC (piston to valve clearance) prior to install to ensure proper fitment without issues of hitting the pistons.

    Hey I'm interested in this cam for my 1995 mustang what springs and rockers do I need?


    • Hi, I suggest using the Comp Cams Valve Springs Item# 30152 and a set of 1.6 Ratio rocker arms to get the most performance out of our you new cam. Here is the link

    I am putting together a 393w, with AOD transmission and 2800rpm converter. Is for an effi pony. Do I recommend the F303?


    • This camshaft is designed for 5.0L Mustangs. Unfortunately, it will not work with a Windsor block that has been bored out. You may need to get a cam designed for a Windsor, or possibly a custom cam.

    i got a vortech v1and if i put a f303, can i keep the original spring valve or we have to change for other


    • Hi, When changing a cam you should also change out the valve springs to assure a long term reliability i suggest using the Comp Cams Valve Springs Item# 30152. Here is the link

      F303 cam

      Great upgrade over stock cam. I already had gt40 aluminum heads and tubular gt40 intake and the difference was noticeable to say the least. Has a lumpy idle and after tuning, it runs really good, I haven't had it to the track yet and it wasn't tuned on a dyno so I can't give specific gains.

      The BANG for your buck

      I highly recommend F 303 cam for the price you will not be disappointed, great sound and performance at about 4000 RPM it really kicks in. I noticed the difference right away. I have a 95 GT 5.0 w/ long tube headers, X-Pipe exhaust and Flowmaster 44's it sounds awesome. On idle its a little low but enough to know your packing something under the hood, but when you stand on it the exhaust sound comes alive with that 5.0 growling sound. It's a great Cam for racing or everyday driving I Recommend replacing the push rods with Hardend Rods and also replace Lifters, thats what I did just to play it safe. Thx again AM.
