Engine Run/Test stand

Hello members. I have a built 340 and a HiPo 273 just waiting to be fired up. Would anyone be able to advise me, share with me, or direct me to a set of plans to build an engine test stand? I do have the front frame rails from a 65 Plymouth Valiant along with the radiator support which would make a great start for the Mopar engines. Basically, I will need to reinforce/brace the unit, but I am interested in the wiring, fuel, starter switch, and whatever else I might need to put this test stand together. Anything anyone can help me with would be a great help. Thank you very much. sgrip65
