Nice stand Mike. On my test stand, I mounted a Ford idler pulley to the test stand's frame that allows me to use one V belt that will adjust to any number of engines. It slides front to back to align with whatever length engine I install on it, and it adjusts side to side to adjust belt tension. I found it easier to use since I didn't have to install an alternator or whatever to run the water pump, I simply use the idler pulley as the adjustment. Since I have built my stand 12 years ago, it hasn't stayed at my shop long because everyone wants to use it.
