    Ford Racing E303 Performance Camshaft 5.0/5.8 (85-95)

    Thanks American Muscle, the camshaft really made a big difference in the performance and sound of my car. Excellent complement to my Cobra intake and GT40X heads

    i like it

    i have one of these in my 94 gt with gt40p heads and an edelbrock performer 5.0 intake manifold. it works very well and sounds great. it does mess with the computer of a 94-95 but not as bad as some others. i do plan on putting some crane 1.7 rockers on soon to give it a little more lift. it is hard to beat the quality and price of a ford cam.

    Classic Muscle Idol!

    Im just turned 17, it took me about 2 days to install this cam and lifters. No one in my family knows anything about cars so i was on my own. This is great cam, nice loopy idol and i noticed a nice H.P gain. Its a nice lil cam to so you wont need to shorten your push rods or replace rocker arms, i didn't even need to shim them. Over all a Great cam for my 94 GT. Suggest you replace timing chain and cam gear, new roller lifters also recommended,

    Awesome Power Gain for my applicaiton!!

    i've got a 91 GT with a 5.0 from a F150 in it, i have port and polished 351w heads with a stock rebuild, had the stock F 150 cam in it so the e303 was quite a power gain powerband seems to be from about 2500 - 5500 rpm on the butt dyno i would say around 40 horsepower could be more but i spin most of the way thru 2nd now and only had a chirp before, that was my application tho. great choice!!
