    has anyone been successful getting fresh air to a motor on a '70 Skylark and or GS other than adding a GS hood and air cleaner?

    Olds had the '69 W31 with the air cleaner and fresh air intakes mounted on the front bumper, just curious if anyone else has replicated or came up with something else?

    You can get the carb hats with different types of tubes on, and then pull some venting tube etc out to the headlights, front bumper and so on.. I considered it ones, but the gains were not good enough for money and work it took doing it..

    When Poston was still in business they made a Buick kit for this.

    The Olds style kit was worth a PROVEN 2tenths and 3mph in the 1/4 on MY setup, every car is different gotta be over 80mph for it to have any real effect, the hats are junk not enough area over the carb to be beneficial. Be hard for me to spend 750 on something that can be put together for 100 tho

    X2 I heard that. The Buick hood on those cars did not work correctly and actually sucked air out when at high speed. I imagine that would be over 80 mph. Probably woks well in town at low speed.

    That thing did not cost no 750.00$ Like hugger said 100 bucks tops.

    What about one of those simple flex hoses leading from the factory air cleaner to behind the headlights/front bumper/inner fender? Probably wouldn't be worth 2 tenths in the quarter, but cooler air is always better than warmer air and should give something. Wouldn't be too expensive this way.

    Pipe in fresh air from the plenum under the windshield. Buick did this in the '68 GS's. When you open the vents air rushes in. Same with getting air from below the plenum.

    Nice high psi area at base of windshield for sure, just gotta hack up the firewall pretty good and would need to be a non AC car

    So, what did the factory fresh air GS hood add other than looking cool?

    Thanks for all the replies!

    Nothing, besides a way for the distributor to get wet

    Here are a few ideas... On my car I can remove two of the headlights to let fresh air flow into the air filters... And on my old car that I sold the new owner routed it so that the air filters actually sit where two of the headlights would be and then he went to modern style headlights that had both high and low beams...

    This was some of the parts Poston had and it is too bad they went out of business since no one really took over any of the extra parts or started to build them. I think they sold it all out and closed it up.

    Should have bought one when they had them since some one thinks they can get 700+$ out of a set up like this but not as nice. The Poston one hooked right up to the front bumper.
