    I'm in over my head

    i assume these are holley carbs? or autolite or something i would guess fuel starvation is your fuel pump good and your fuel filter clean changing the idle screws should not really have an affect on your cruise you'll need to change the jets to richen up the mixture

    66 pic (photoshop)

    before reading you post, i thought man that car would look super sweet if it was lowered lol i got some 600 lbs 1 inch drop front coils (it was like $30 bucks a piece) and it made a world of a difference in the look and handling of my car changing the spring is super easy - i thought it...

    Why does my car shift so early

    you can manually keep it in gears 1 and 2 as long as you want but watch out, i blew out my 2nd gear clutch on my c4 if your on the highway, throw it all the way down, and the tranny will shift into second if you have it in low from a start, it wont shift out until you do it but what i did...

    Adding a hood scoop, and am afraid of water

    the scoop is a 69-70 mach 1 scoop the whole is lined with 3/8' fuel line but i have no idea how much water, if any, comes through ive never had any problems though but your whole will probably be much wider than mine the plug mentioned before is a great idea

    About how much HP/torque?

    no bigger carb if you get an edelbrock the combo you have listed will make some real good power thanks to the nice heads of course, a 331 with that same stuff will make more horsepower but it may not last as long; and its more expensive it all depends on if the extra bit of torque and...

    Adding a hood scoop, and am afraid of water

    on a street car, ram air doesnt actually add much horsepower the cold air, that goes through a scoop, now thats a different story and cowl is less likely to get water and will feed probably more cold air under your hood get a K&N filter (more resistant to water; recommended for boats)...

    Yet another H/P *estimate* request.

    with that huge cam, you could probably make a ton of power with some new aluminum heads the shelby's were probably rated with no accessories im gonna guess 300 at 6k rpms i dont think your low end torque is going to be all that great
