Big cam snap test

Can someone point me toward what tools and process I need to do a snap test on my Big Cam 1? I've turned it up and want to see where my pressures are at. Thanks,

Radiator pressure tester. Replace the hose assembly with a pushloc one and a #4 male JIC on the end. Connect that to the end of the steel line that screws on to the after cooler. Pump it up to 20 PSI and run the engine to full throttle quickly. Snap pressure is maximum before the governor cuts it back.
