    So..I have a lead on a Super Wildcat dual quad buick 425 engine..still bolted to its super turbine 400.. Cast iron dual quad intake and carter carbs still intact. Less than 200 made in 1966, down side is the engine is very..very rusty. I will buy it if im able to, and play my cards and hope it isnt stuck.. if it is stuck well then... il have to free it up :p

    sorry no pics... but i will get some if im able to.

    You don't really want that rusty pos do you? Alright ,I'll take it off your hands and dispose of it properly. lol
  3. that is the holy grail of nail heads and the best engine trans combo that Buick ever built. even as a core it will be worth it's weight in parts. IMHO......Jim

    Great motors with a load of torque at 2,800....even with radical cams, they're still stump pullers in the low-end. Here's a 401 I just finished:

    i found one in a brown 4dr hardtop sitting in a wrecking yard years ago. I'd seen the car in there for months, and nothing was taken off it anywhere. I was looking for throttle linkage and opened the hood-what a suprise! Totally complete and untouched. I asked the yard owner what he wanted for the engine, and when I told him what it was, he was out the door and past me before I finished. He had a 63 Riv he was working on and that 425 was dangling on a hook in 15 minutes.
  7. You said it! I just agree with you.....Jim

    A friend just sold a factory original dual quad on ebay for a little over 800 bucks so anything less and the engine would be free!

    Yes, that's the factory color from the 1950's. It's available from Hirsch Automotive:

    You have to shoot it with a gun, but it's by far the best engine paint I've ever used.

    ribbed and that monster super wildcat dual snorkel air cleaner. I am rebuilding it
    currently and adding a ribbed valley cover and polished stainless bolt kit hei distributor head flow work taller cam and 1.9 ratio rollers. Adding some chrome
    accessories such as alternator and radiator cover. Just a slight dress up.

    I'm an absolute, diehard Mopar guy, but, some where in the late 70's early 80's I bought a 64 Riv from a friends little brother. He bought it from his high school's auto shop. It was donated for the kids to work on. It was a full opted car. I don't think they had a Riv GS in 64. It had 425 dual quad, alum. valve covers, giant chrome air cleaner, AM/FM, power ant., power seats, power windows including the wing windows, auto head light dimmer, finned alum wheel covers, air, cruise. If Buick offered it it was in there. By far and away it was one of the coolest cars I have ever owned. That monster would run 14's all day and eat the so called performance cars of the late 70's alive. The most fun I ever had with it was trouncing one of those Smokey and the Bandit turbo 6 Trans Am's. Maybe he just chickened out, but I was real close to pegging the 140 speedo. That's the fastest I've ever been in one of my street cars. Maybe the old chicken out got to me after that, Joe.

    A few pics of our just driven '32 Highboy with '63 401 Wildcat with 2x4's, GS+ cam, MSD ignition, and Sanderson headers running through a Muncie M-21 and 9" Ford rear end with 3.70 gears.
    To say it runs well is an understatement - enough to blur your vision in all four gears - and at 70 mph in 4th gear you are right in the peak of the torque curve - 2800 rpm.
    We were going to build a 63 "Corvette" type solid lifter small block, but decided to do something different. Getting the nailhead to fit into the car presented many challenges - like keeping a "simple" mechanical clutch linkage and getting the brake pedal to not hit the starter.
    We were fortunate to have excellent advice from Jimmy Shine at SoCal Speedshop in Pomona, inspiration and beautiful craftsmanship from Danny Burroughs at Bruce's Rod Shop in Spring, TX on the frame engine mount, buick brake drum machining and beautiful work from Bob Gleim of Bakersfield, Ca on the "shuffled' 2 in. forward motor and trans mounts and clutch linkage - Bob is a recent winner of the Grand Marshall's Award at the Bakersfield March Meet for his 30 Highboy. We also did one heck of an amount of research on Nailheads - there are alot of "posers" and "experts" out there - BEWARE!!!!!
    We also received consistant motivation and encouragement from our fellow Houston Roadsters - my 14 year old son Blake and I did all the rest of the we get to drive it and have fun!
