    My setup:

    1994 Cobra - Stock 5.0 block:

    - SVO Aluminum GT40 Heads

    - Stock Cobra Upper & Lower

    - BBK e/l Shorty Headers

    - BBK o/r H-pipe

    - BBK CAI

    - Aluminum Driveshaft


    Made 260rwhp / 300rwtq on a dynojet. Should I be making more power or is this typical for my setup? It was running a bit lean as you can see on the dyno sheet:

    Add a better cam and long tubes, numbers seem right for your mods.

    What's your timing and fuel pressure set to?

    It's not too far off, depending on rockers. Ford went with the 1.7rr and used a smaller cam in the 5.0 Cobras. My setup with iron GT40Ps, GT40 intake, E303, 1.7rr comes in at about 275/310 with aggressive timing. Tuned down it's at 259/307 IIRC, that's a non-tuned 94 GT ECU.

    That's just where I'd expect it.

    Numbers are solid, don't forget about drive train loss, with that in mind you are close to 300 hp at the crank. +1 on a mild cam, but if you keep the stock bore/stroke your shorty headers are just fine.

    Oops, wow, I can't believe I forgot to mention the cam. I'm pretty sure it's either an F303 or a B303. I didn't install it and the guy before me didn't know much because he had a garage do all the work. I'll get a video up so you guys can hear the idle. Timings at 14° right now. The ECU is also chipped with an outdated autologic 2004.

    It was just two pulls without any tuning. I just wanted to know what power it was putting out. The autologic 2004 chip is no longer supported by anyone on the planet, lol..

    Well, in my opinion, it would cost a whole lot more than its worth to tweak things now and get another 10-ish HP. You could bump up the fuel pressure a bit (if adjustable) to bring the A/F down a touch, but I wouldn't mess with anything else unless you're planning major changes.

    I don't know if anyone's ears are *that* good. :)
    It doesn't sound that much different form my Steeda #19, though.

    A stock 94-95 Cobra block runs with a E cam I believe but I could be wrong.

    You are wrong. If you're saying a E303 is in a 94/95 Cobra. If you're saying a 94/95 Cobra will run with a E303, then yes it does.

    Sounds just like my car with my b303 but honestly it sounds like others with plenty of different cam's.

    So no we can't tell you by sound!!! Lol
