    swappin the intake and exhaust manifolds, feeding the engine through the exhaust port

    i read this some where and was wondering if this is a viable thing to do. is it wise? i just bought a '66 riviera 425/4BBL

    it was done on a full on drag car with a turbocharger(?) back in the 60s.

    it was used as a way to get around the small restrictive valves ( apply more boost to get the intake charge past the smaller "exhaust" valve and get rid of the dogleg intake manifold runners altogether ) in the Nailhead.

    fitting all of the piping to route two separate intake logs could be a serious problem in a factory installation setting. and i would think you would want to plumb it with port fuel injection so you wouldn't have to worry about fuel dropping out of the airstream in the intake logs. it would also require a custom cam.

    i don't think doing it would be cheap.

    Well, I had to crack up when I read this. I think it was a noble experiment, but it would be better to turbo charge if you want to
    get more power. I think it was on a boat though...(i'm) often wrong, seldom in doubt

    here's the car i was talking about:



    it's in a Car Craft magazine article:

    from Feb 2009:

    one thing to take note of is the silly angled exh pipes. instead of forcing the exh to make a 90* turn to the outboard side of the engine, i would just attach straight pipes to the 'intake' ports and allow the exhausts to interleave.

    that might create some major vision problems for a rear seated, centered driver though, which is perhaps the reason why they did that in the first place.

    you also see that they were running 4 pull through carbs.
