    Hi Nardo.
    The subject has been done a few times before.

    Some good contacts of suppliers are in here.

    What do you want to use the car for?

    Daily drive? Weekender?

    This is a good starting point:

    That combo was with standard valves, ported head with a 500 Holley on a match ported standard inlet manifold.

    Loads of compression with a good "rpm 90" clutch.

    Balancing the bottom end will help a Pinto engine rev to 7000 rpm with a standard flywheel.

    35(BTDC)+180+75(ABDC) = 290 degrees duration. Tighe 924 grind. I picked one up recently with a bunch of other stuff - have no plans to use it as I'm after a shorter duration and higher lift for torque > power. Has 0.425" of valve lift, cross drilled, matching rockers.

    Getting followers with a cam is best. some suppliers have different rocking ratio's. this all depends on valve stem lengths.
    It will produce power from 3500-6500rpm. mine was a dog under 2500rpm.

    I would go for Avon's cam if i needed one.
    Remember, it won't need the spray bar anymore being cross drilled.

    The oil feed will need blocking off on the side of the center cam post, where the oil rail bolts on.
    Oil feeds the cam via a slotted center cam bearing.
    It's not straight forward, but worth while if you don't trust the spray bar to feel oil to each cam lobe.
