  • Headers or Magnum truck manifolds


    I was wondering is any of you are running headers on your late model small block B body? What are your experience with installation and fitment on your car with A/C and power steering?

    Anyone run the late model 92 to 93 5.9 truck manifolds that supposedly flow as well if not better then the the 340hp manifolds?

    I've heard the small block Magnum exhaust manifolds flow pretty decently but don't have any experience with installing them on the cars. I would think it wouldn't be that hard to do though.....

      Look at the engine photos I posted on your 4bbl thread, I have headers on a couple of those motors. On the BB I used Schumacher. On the Imperial I used an A Body Tri Y.

      With a mostly stock small block I don't think you need more than a Tri Y, or 1 5/8" primary shorty for B Body.

      On the intake, I used the non EGR Performer (Air Gap is too tall for Magnums).

      While Improving under hood, the aluminum brake master cylinder is a good upgrade that looks and works better.

        I spent the afternoon at the local pick a part and scored a set of 92 Dakota exhaust manifolds, couldn't beat the price so I am going to give them a shot.

          A Dakota V8 in a junk yard?? Man, finding one on the road is tough enough lol. Been looking for a decent regular cab early 90's model for awhile now. Seems like most of them are extended cab.

            I was lucky the local pick a part has 3 yards and about 30 Dakotas, and the most of them are the later body style of the 4 square trucks only one was a V8. They even had a 67 dart but it was pretty picked over

              So I scored a set of the early magnum exhaust manifold that are supposed to flow equal to or better than the 340 hp manifolds. Part numbers are #53006618 and 53006619 I mocked them up and the seem like they are going to fit my magnum just fine. The outlet in 2.25 the later ones are 2 inch and 1/78 on some I have heard but can't verify.
