I can give you a rough estimate tomorrow. I'd be interested in seeing how you are going to mount the rack in that location, I've thought about doing it. It may not be possible with the torsion bars as close as they are.
Thanks Stacked that would be appreciated. Someone over here developed a system that you run wings off the back of the k-frame which you mount the steering rack to. My father has this system on his a-body and I have the standard system on mine, however he runs a hemi 6, but I'm putting the new hemi in. By looking at that picture I uploaded height seems to be the only doubt at this stage. I may have to put in some spacer plates under the engine mount insulators depending on the clearance.
