1-3/4" BIG BLOCK HEADERS

PART NUMBER:  383440-134

HEADER FEATURES

• 1-3/4" O.D. Tubes

• 3.0" Collectors

• 3/8" thick Flanges, laser-cut, contoured for a leak free fit

• Under chassis design:  Above the steering center link design offers maximum header to ground clearance

• Full length header design:  Proven power gains vs. shorty header designs

• Recommended Horsepower:  300-475

• Torsion bar removal:  Not required in B & E-body applications, however, removal recommended in A-body applications

• Header Material:  Constructed of 16 gauge mild steel tubing.  Mandrel bent on sophisticated computer controlled bending machines for precise fit and uninterrupted exhaust flow. The mandrel bending process maintains a constant inside diameter of the tube for a smoother finish with no restriction of flow and no crimping of the tubes.

HEADER FITMENT

• Our headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.  (Click here for the factory dimensions)

• Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations.  However, we have done our best to accommodate both factory and aftermarket component combinations.  In some cases, slight modification or repositioning may be required on your part to clear the specific situation.

1.  PLATFORM:

67-76 A-BODY, 62-74 B-BODY and 70-74 E-BODY

2.  ENGINES:

383-400 B-ENGINES & 440 RB-ENGINES

• Headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.

3.  CYLINDER HEADS:

OEM or EQUIVALENT - Factory 915, 906, 452, Bulldog, Edelbrock E-street, Edelbrock Performer RPM, Indy-EZ, Stage 5, Trick Flow, 440-Source

• Cylinder Head Studs:  Head studs may be used on the Passenger-side, however, the header tubes will not clear the cylinder head studs below the #3, #5 and #7 cylinders on the Drivers-side.  We recommend ARP bolts for clearance in these areas.

4.  SPARK PLUGS:

STRAIGHT or ANGLED

Headers are designed with adequate plug clearance for angled plugs.

5.  FRONT SUSPENSION:

OEM or EQUIVALENT with torsion bars

COILOVER without torsion bars:  The following coilover systems have been fit-checked with these headers and found there to be no clearance issues...  RMS Alterktion, Magnumforce Tubular, Magnumforce Modular Transformer, Control Freak

• Steering Linkage:  OEM with torsion bars or Rack & Pinion without torsion bars.

• Steering note applies to 67-76 A-bodies & 62-65 B-bodies Only:  This header will not clear a Quick/Fast Ratio Pitman & Idler arm that is longer than the OEM arms.  Example; The Fast Ratio Pitman & Idler arms by Firm Feel, Inc. are 3/4" longer then stock.  DIY clearance can be achieved by dimpling the header tube(s), however, doing this modification will void your header and coating warranty.

• Clutch Linkage:  OEM

• Keisler/Tremec TKO-500/600 Transmissions:  It is imperative that the output-end of the tail shaft is in exactly the same position as the stock transmission output shaft for the headers to fit properly.

• 67-76 A-body applications:  A modified Z-bar will be required, sold separately part #ZB307.

9.  FLOOR SHIFT:

YES

• Auto Trans:  Some applications with an auto transmission may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector, see illustration sheet #3703
