    I need help guys! After researching for months I still cannot figure out what long tube swap headers to purchase for my 1971Camaro with a Gen III LSX motor (LQ4) with muncie 4 speed, and I am using the Zbar clutch linkage with SDCB pivot ball adaptor. The motor is installed with the 1" Carshop setback brackets and standard small-block rubber motor mounts. The rear transmission mount and cross member is stock GM, and the transmission tail housing bolts in dead on, so I do not want to change the motor mounts e.g. Hooker/Holley mounts. Hooker swap headers fit with the zbar but they say they won't install with anyone else's mounts, which I find hard to believe. Also many people recommend using the 75-81 Hooker swap headers because they tuck up better. I think that Kooks headers will work with my set up, but they are extremely expensive. The Dynatech swap headers will work but everyone says they hang down too low. Please does anyone have advice for me and some picture would help too. I will post this over on the ls1tech site for input as well.

    If they allow you to return the headers , buy the ones you can afford , and afford cash hit if you have to return them, and see if they fit , all of these cars are off by a little , and even if someone said they will fit your application perfect, they may not , so take a chance , and decide how hard it would be to make , what you can afford fit, it you decide it is to much trouble then return, if not , give them a bag or two and get them in there , so you can start driving your car,
    just my 2 cents

    Thank you for your response does anyone know the difference between the hooker headers for the early 70-74 and late 75-80 fitment in terms of collector height? Some header companies give a dimension down from the manifold at the head to the top of collector.

    Are you willing to modify them slightly? Ive got fourth gen camaro long tubes. You need to bend the collectord to make them fit. The z bar does physically fit but you would need to be crafty making a mount. I was going to do this but i got a hydraulic setup for free so I said why not.

    Dynatech and I have a set for sale.
    See my thread in this forum somewhere. By the time figured out how to adjust everything from Novak adapters website, I went with the McLeod hydraulic because I was out of time and needed the drivetrain installed to move for a new job.

    I used Dynatech headers, carshop 1" setback mounting plates and stock motor mounts. The headers do not set low with stock motor mounts and these plates. Use this you will save your self alot of headaches.

    I wouldn't mind going with the Dynatech headers, but it would be great if you could share some pictures of the headers installed with the Carshop mounts, I looked and can't seem to find any good pictures. Most pictures I have seen in the past always show them hanging way down, so it would be nice to see them sitting higher for once. Also I have seen some different part numbers for the Dynatechs, are there different versions now or just one? I will call Dynatech too.

    When we are talking hanging low, there is another part to this equation. That part is your car's suspension which places the car lower to the ground too. What springs are you running?
    my thread shows mainly the dynatech headers installed with the exception of the underneath shot which is the stainless steel works. The side by side photo is a good comparison but from memory dynatechs were about 3/4" below the frame, pretty much where my hooker super comps where. On very low eibach springs, they dragged on some inclines and speed bumps if you didn't think ahead and angle it. Also carshop 1" set back plates.

    Erik,
    I am running Hotchkis 2" lowering springs with stock subframe mounts. The wheel/tires combo will be as close to stock diameter as possible in the future. Did you ever try the Hookers with the Carshop 1" set back plates, a can't imagine that the hooker mounts would put the engine in such a different location, but they say their headers won't fit with any other type of mount? I like the way the the Hookers are designed, as the primary tubes drop straight down. I am not a big fan of the crossover tube design as the spark plug wire are impacted.
    Thanks Pete
