I'm just stumbling onto this build now so I appologize if its mentioned in another thread, but...
What are you doing for a ps pump and lines to the steering box?
I have a gen6 454 in my engine bay which has the hydraboost pump, but I'm stumped at how to plumb it to my steering box. (my truck is an 82 K20)
I might just end up going to a 1/2 ton vortec ps pump instead just to keep it simple as I don't have anything else from the hydraboost setup.
Sorry for the hijack.
