      1 7/8" headers - SBC in a 68 Firebird !

      Hi Guys,

      I currently have a set of old press bent 1 3/4 " long tube headers on my 421SBC in my 68 Firebird. The engine made 580HP & 550ftlbs but is running no quicker at the track than it did with the old engine. The pipes are down to smaller than 1 5/8" on the press bends so I am thinking this wont be doing me any favours.

      I was looing at fitting a set of Hooker Super Comps on the car but have seen too many pics of them hanging down low so crappy ground clearance.

      I am now looking at either the Dougs 323 or the Dynamax 740- 21310. Both of these are a stepped header from 1 3/4" to 1 7/8".



      My car is lowered & runs all factory Camaro stuff so there should be no drama getting a set of off the shelf headers for it.

      I also run AFR angle plug heads.

      Have any of you guys ran either of the above headers & what can you say about -

      Spark plug lead clearance ?
      Fitment around steering box ?
      Ground clearance ?

      Thanks
      Scott

      Scott,

      Ultimate Headers has a new SBC 1 7/8" header for a SBC in a First Gen F-body! If you email me, I can send you more information and pictures.
