    Very cool and very rare! Tell us more- how did you find it?
    Wild Bill and I are the only folks I know of with this action!
    Here is mine:


    How tall is yours? Wild Bills id the same as a cast iron 2 x 4 manifold,
    mine is about 3/4" taller and the carbs are 1/2" further apart.

    Topcat Got TORQUE?

    WOW.....did'nt think i'd ever see any more of them pop-up :pp

    Here's mine.......it mounts the stock air cleaner.......i've never weighed mine but i would be suprised if it was over 5lbs......them things are LIGHT !

    This one does not have any mount holes for the coil or a vacum port.......


    I may have mine off for some clean-up before the Wildcat Nationals and i will try and remember to weigh it.

    Peace WildBill

    Hi all! To answer some questions:

    Yes, I did get it off Ebay last year. I took a gamble on it and it turned out to be really something special.

    Story goes, I purchased it from a factory GM engineer in MI. He and his co-worker were instructed to clean out the R&D room in the mid-70's and scrap everything. They disposed of everything, but he chose to keep this intake and his friend kept two of the earliest q-jet SBC intakes he has ever seen(supposedly still has them, too). This intake remained in his tool box-wrapped in a blanket- at work for the remaining 30+ years until his retirement. When he retired, to protect his pension, he smuggled this intake out in a shopping bag with soda cans on top through an unmanned gate when he left. He told me that if GM caught you taking any of their property off site, it would cost you your job and pension and he was not risking that. He also told me that this was the only item he smuggled out, but ended up trashing tons of amazing stuff that was too much to bring out. He ended up selling this intake on Ebay to help fund his 32 Highboy project(has a Chevy motor....). Was a really cool guy to talk too. I may even still have his number somewhere.

    Compared to WildBill's, mine is a rougher version. Perhaps an earlier prototype. Does not have vacuum port on it, but does have the coil mount on the rear. Dimension wise, it is identical to a regular 64 dual quad intake I have. It weights maybe 8-10lbs.

    Since a few people have asked, I would consider selling it if the price is right. Email me to discuss.

    Thanks again to all for the id help! Will have some neat Nailhead stuff to be posting on here soon. I am currently building a 425 .030 over, coated pistons, Total seal rings, custom cam, Tom's rockers, heavily ported heads, TA headers, etc for my 64 dual quad car. Should run ok, hoping for mid-high 12's in the boat. Also am pioneering a tubular adj. bolt in rear suspension for 63-65 Riv's, should have more info on that in about a month.

    Didn't one of the companies that produced intakes in the 60's or 70's make a aftermarket aluminum intake for the Nailhead motor?I think I have one in storage somewhere. Tom

    A deceased friend of mine was a big wig at the Flint plant from the early 60's to the late 80's. He said that when they re-roofed the plant (early 80's) the maintenance guys found Stage heads resting on the rafters of the roof where they could be yanked by someone and taken out the back door at an opportune time.

    I would like to know what the price of that dual quad aluminum manifold works out to PER POUND!?!?!?
