That's exactly why I built mine. It makes re-torquing, installing inner springs, and the stupid leaks easy to do. The first engine I ran on it had a freeze plug that seaped. I fixed it in 10 minutes sitting on a milk crate. In the car would have sucked. It also lets me get real world numbers for idle vacuum, cylinder pressures, oil pressure and water temps and make sure the cam's good before the customer gets it.
