Has Anyone Used the Holley/Hooker Exhaust Manifolds?

It would "appear" that the hookers would fit mine. Last I checked though, you didn't offer stainless steel for the LS swap application. Why is that?

On the other hand, I've got to do something about my subframe now that I found it's pretty crappy. Don't have an extra one laying about do you? LOL

You have to be careful making that assumption of fitment as the new Hooker bracket kit retrofits 1973-up clamshell mounts into the car and are quite different from any swap plate/frame stand set-up. The biggest difference would be the clearance that allows splitting the tubes around the steering box, and the engine height position that is obtained with the mounts. If the height of your mounts is greater than you will not be able to acheive the 3 degree engine/transmission inclination angle we desined into the componenents without having interference issues between the collectors and the floor. That would result in you having to tilt your transmission down at the tail end lower the collectors at the expense of worsening your U-joint working angles. Although the may or may not bolt-in with your mounts, they were in no way designed to do so and provide optimized fitment/operational geometry in your finished package.

As a final comment, Hooker does offer all our LS swap applications in stainless along with all the premium components you'd like to see with the upgrade in material...here's a shot of the stainless version of the same header, notice the investment cast flanges and formed merge collectors that differentiate these headers from their mild steel siblings.
