    Seems like I have been burning up the message boards with questions lately!

    Ok...I am building a 302 for the Mav. I originally was going to go with the 268H comp cams package but thanks to everyone here that may have changed. I have decided with a little help from everyone here, that I am going to put a 4spd in the mav. Here's the specs:

    ported stock heads 9.4:1 compression
    stock valves with rollers rockers
    long tube headers
    30 over bore
    holley 600
    3.00 gears
    4spd toploader

    So, should I stick with the 268H that I was going to use with the c4 or something different for the 4sp. I would like the car to be able to idle please. This will be a daily driver.

    Thanks
    Jim

    are you looking for a solid flat-tappet, hydraulic flat-tappet, or one of the rollers? I'd shoot for something along the lines of about 230 duration @ .050", around .525" lift, 108-110 lobe separation angle. Should work well with the 4-speed.

    I've got a 268 in my 302.

    Build specs-

    302
    bored +40
    268 cam/lifters
    long tube headers
    still got motorcraft 2bbl though
    all new bearings

    Think that's it, but I probably forgot something.

    Even with the 2 bbl., I got 103 in the quarter on the highway, and have run it over 130 (no I'm not just spouting off at the mouth either:rolleyes: ) With this cam, the engine lopes nicely. I get a lot of comments on the way the engine runs and sounds. Good luck with the project. Country

    it is going to be hydraulic cam. Cant afford the fancy stuff or I would go with a roller. If the 268h has a lope to it, I doubt I will want to go anymore radical. Still....a little more cam cant hurt, can it??

    :D
