Cams I wanted to know what is faster a E(303) F303. I just want to know which cam makes a different performance but that is street legal.

MuscleHead90

  • Both Cams are street legal and I think the F cam is a little more agressive than the E cam. If you go with a X or Z cam they are made for racing applicaions I have the F 303 in my 95 Gt and I love it. Highly recommend replacing the rods with hardened rods and the lifters

carberated will this cam work on a carberated engine

carbman

  • Yes it will if the engine is set up for a roller cam, but note that it is designed for an EFI engine. Your best choice is to call a cam manufacturer or the guys here at American Muscle and let them help pick the best cam for your application. Good Luck!

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.

GaryDon

  • 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.

Question Resolved

Is the f-303 cam a good choice for a 306 with a vortech supercharger ?

87gtcobra

  • The Ford Performance F303 Performance Camshaft (85-95 5.0L) would be great for a 306 with a Vortech Supercharger. The F303 is a perfect Cam for supercharged Mustangs.

Question Resolved

What max horsepower power range is this cam rated for?

Sn94

  • I had this cam on my Keith Black 306 bottom end with gurdle and windage tray, tfs street heat heads, Vortech upper Truck lower intakes, 70mm throttle body, 42 lbs injectors (not enough), 1 3/4 inch headers, 3" header to tip mac exhaust and a Vortech S Trim blower with stock 6lb pulley, Anderson Ford PMS electronic box for tuning. On Mustang dyno made 565 rear wheel hp, and 540 lbs of tourque. Injectors were maxed out, my only mistake. All street/handlimg suspension ran 10.65@124mph...Great cam but if using with stock block stick to 1.6 ratio rockers as .512 l8ft is pushing the stock clearance limit. B and E 303 no clearance issues with stock at jist below .500 lift...Hope that Helps...Good Luck

    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.
