What's in the Box

Info

If you are lucky enough to have a GM small block crate motor with D-port heads (FastBurn, ZZ4, etc.) you will find that regular headers just don't work. These block hugger headers were specifically designed for these heads. Features 1-5/8" primary tubes and 2-1/2" collectors with 2" reducers. Includes bolts and gaskets. These shorty headers have a tight-tuck design for narrow frame rails to make difficult installations easy.

  • Collector exits parallel with the oil pan rail for maximum ground clearance
  • Made from lightweight & sturdy 18 gauge tubing
  • Tight-tuck design for narrow frame rails

Will these headers fit in a 1977 corvette? also, do you offer a full length header for this application. D shape ports in a 1977 vette? I plan to install a ZZ383 with fast burn heads. Port sizes 1 7/16"w x 1 3/8"h. D shape. Would prefer 3" collectors.

These headers are specific to the ZZ4, Fastburn, or D-port heads. Verification of fit to your application requires some basic measuring. From head surface out 4" to the furthest point on the tubes, from top of the flange to bottom of the collector is 10", and the collector flange sits within 1" of the block. The collector is directly below the center two ports on the heads. We currently only offer these with a 2-1/2" collector. Sorry, we do not currently offer a full lenght header. Tube O.D. : 1.63 " Collector Diameter : 2.50 " Flange Style : D Port Flange Thickness : .38 " Port Height : 1.56 " Port Width : 1.51 "

Are these headers a good choice for a ZZ4 crate motor in a 65 vette with factory side exhaust?

Speedway part number 9302300. These headers are a universal block hugger type design. We do not have listings for each make and model they will fit. Please use this header chart to get the dimensions for these headers. This will help determine it they will fit for you. http://static.speedwaymotors.com/images/charts/9302300.gif
