    Speedway Motors 930C8 Details

    Classic Chevy owners will love these 396-502 big block V8 chassis headers for 1955-1957 cars. They have 34"-36" primary tubes for lots of power, but they're tucked close to the body for maximum ground clearance. Requires aftermarket side engine mounts and a rear trans crossmember (rather than stock bellhousing mounts).

    • Mid-length design offers maximum ground clearance, even if car is lowered 4"
    • Works with automatic transmissions only
    • Designed to work with stock steering or 605 power steering box
    • Original bellhousing frame mounts must be removed
    • Will NOT work if engine is set forward more than 3/4" for firewall/HEI distributor clearance
    • Will NOT fit tall-deck (truck) blocks
    • Includes a pair of reducers (3.00" to 2.50")

    Note: These headers will not work with manual transmissions due to clutch linkage issues.

    Application

    1. Will not fit if engine is located more than 3/4” forward for HEI firewall clearance. Fits with TCI engine mount kit PN 725-7005-80 and with the equivalent Danchuk mounts.
    2. Header is designed to fit cars using original V-8 pitman arm part number 3719487 not 6 cylinder pitman arm number 3709877. Aftermarket pitman arms must be same configuration as OE for proper header fit.
    3. Works with A/C, P/B, P/S, and A/T (both column and floor shifters).

    I really wanted to make these headers fit with heating and denting and modifying, but there was so much obstruction I could not envision them ever being able to fit without caving them in at least halfway

    Would Not Recommend

    Will fit with some modifications

    These look to be high quality construction. Too bad they won't fit between the stock suspension, won't clear the a-frames and sits against the gearbox pushing the engine 1 1/2' to the right.

    will these headers fit a 366bbc in a 1956 chevy with pwr steering? After installing the engine, there is only an inch and 1/2 clearance between the 3rd exhaust whole on the drivers side and the original steering box. Your cooperation will be appreciated.
