This Pair of Southwest Speed Fenderwell Headers are great for Hot Rods, Street Rods, Rat Rods & Nostalgia Rods, and are hotter than ever. Designed to fit over the frame rails and exit inside the front fenders at bottom of the cowl, these headers are perfect for that Big Block Chevy installation in the popular Tri-5 Chevys. Using the fenderwell design allows the primary tubes to be longer, greatly increasing performance.
350" flanges on the cylinder head surface with 2" primary tubes, these headers feature 3-1/2" collectors and are supplied with 2-1/2" reducers that bolt to the collectors, to connect the rest of the exhaust system to the vehicle. The Header Flange is a 2 Round Tube at the Port and will bolt to all Big Block Chevy Heads, with no spark plug or spark plug wire restrictions, although we strongly recommend running the spark plug wires under the headers.
These Headers require either cutting or removing the inner fenderwells. For this reason, we only suggest these headers for experienced builders.
Not for lowered engine applications. Stock bellhousing location is imperative for these headers to fit Tri-5 applications. These headers fit tight above the steering box and in some applications, may require minor grinding or changing of the steering box adjusting cover bolts. The stock emergency brake rod must either be altered or removed for these headers to fit.Large front tires also interfere with these headers in some instances, depending on front engine mounting location. Note: We strongly suggest you refer to measurement chart below to insure headers will fit your vehicle and application, before ordering. 2" primaries to the 3-1/2" Collectors. Includes 2-1/2 reducers to connect exhaust under the vehicle.
Great for Hot Rods, Street Rods, Rat Rods, & any Nostalgia Rod. Nice Choice to replace cast iron exhaust manifolds. Enhances the looks of any rod. Includes gaskets and mounting hardware.
Painted Flat Black to resist early corrosion. Fits all big block Chevrolet V-8 engines with standard exhaust pattern. These headers are designed for 1955 to 1957 Chevys that have had a big block Chevy engine installed in the relative stock location, using the stock 1955 to 1957 Chevrolet bell housing and transmission position as the reference for stock location.These are not designed for vehicles that have had the bell housing or transmission position altered. These headers do rise up coming out of the exhaust port to clear most frame rails.
We have seen these headers used successfully in many different applications using the big block Chevrolet engines, but we strongly recommend you refer to the measurement chart below before ordering to insure these headers will fit your vehicle and application. These headers are painted with a high heat dull black paint. It will generally dull even more when the engine is started. The header paint will smoke and let off an odor the first few times the engine is up to temperature and the black finish will become duller turning closer to gray in color.
If exhaust temperatures are extreme at start the paint will blister and peel. Please refer to the header measurement chart below to make sure the header will fit your vehicle and application before ordering. Use care when trial fitting headers.Repack them well to prevent damage returning them to us. We also have these same headers available in.
