'65 Wildcat hood clearance with dual quads?

    I'm planning on adding dual quads to my stock '65 Wildcat single AFB and wonder if there is sufficient hood clearance for an Offy intake, later Edelbrock 1406 carbs, and small 6" Spectre brand air cleaners? Any help is appreciated. I know that there is a 3/8" difference between the low and taller Offy dq intakes, and I would prefer to run the taller of the two intakes, provided there is room. Additionally, Is it necessary to use a small body distributor in order to clear the intake and/or rear carb?

    Les- I am running a dual quad intake that is 1/2" taller and have clearence issues with my minimal air cleaners. The Offy's have a terrible reputation.
    The stock dual quad does just fine!

    you can always mill the top of the intake for hood clearance. what kind of time and mph did the big car do on the race track ?

    I wouldn't recommend an Offy intake either. They don't flow well without modification, and it's height will be a problem.

    A stock 2x4 manifold would fit best. They've gotten pricey, $700-ish.
    There was an aluminum intake made by EELCO not too long ago (10-20 years) that is a good choice if you can find one. It's a copy of the old Edelbrock manifold. It's a little taller than stock but you can likely make it work.

    Or just put a single Edelbrock AVS 800 cfm carb on it, they supposedly work well.

    I have a confession to make: so long as it doesn't cost much power on my 47,000 mile stock engine, I'm in it just for the appearance!

    Wasn't even more like 50 HP less?
    Someone showed a pic of one to where you couldn't even put your pinky finger between one of the back side ports into the carb hole.
    Unless you get this Offy intake ported to work I think the power loss will be really bad.

    I remember a thread a few years back about manifolds; the consensus was that The Offy dual quad manifold was awful, as in awfulhouser.

    OK, you got me with the "awfulhouser" comment! ;) Thanks to all for your input and counsel, I scored a stock dq intake today. :)

    Good choice.

    Feedback: following the counsel of my esteemed fellow members, I obtained a decent used oem intake :). Then I added a pair of Edelbrock 1406 carbs, and twin 6" Spectre air cleaners.

    With everything stacked upon the 401's heads I had almost an extra inch of hood clearance to the hood with the old insulation removed. :cool:
