    So far I can only find information on one site for this type of blower. I'm looking to see if there is a specific name or type of blower that the older muscle cars use. If I'm not making sense take a look at the pics.

    Thanks.

    Yeppers, that's a roots type blower... Usually identified by a set of numbers like 6-71, 8-71, 12-71, etc. with the larger first number indicating a larger blower. Most street applications wont go above 8-71, anything more is a little overkill on the streets.

    A bit of trivia... The Roots type blower is named after a couple of brothers that designed a system to force air into mines and other low oxygen or hot areas. Originally designed as a water pump, the device failed but the brothers realized it could move air much more efficiently. The kicker? This was back in the mid 1800's, making the Roots type blower the granddaddy of supercharging.

    So the superchargers are just a basic roots charger, but the part that pokes out from the top is just like a ram air system to get more condensed air with an air filter?

    First ones a butter-fly scoop, and the following two are bird catchers.

    Is there any specific function to the butterfly scoop over the open bird catcher type and vice versa?

    The reason why they stick out from the hood is because the roots supercharger mounts ontop of the intake manifold, then the carb and the air cleaner. The scoops prevent the air from moving to fast/ look good.

    Now, can you get the scoop without having a blower? In the Summit catalog I was looking at it appeared to be that you could. However, according to what Jonjolt said, because the S/C sits on top of the intake, the scoop would sit much lower if you didn't have a blower, right?

    Not unless if you had a high rise intake, which isnt too good for street use.

    So then it would be best to get the blower and then the scoop.

    You can but it would look ridiculous, I've seen it. Single carb spacers to raise it up. It doesn't look right unless you have dual carbs and a tunnel ram or SC. This would work.
