How to prepare for engine dyno?

Dyno a motor. Getting ready. I would say get over there and look at the set up. See what it takes to mount the motor onto his cart. His set up might bolt directly to your block. Or you may need to bring motor mounts. Will your motor plates work? It all depends. Does he have a plate that bolts to your crank that accepts another plate that's spliced for the dyno input shaft? What if you need flywheel bolts and you got flex plate bolts? Does he got dyno headers? Will they clear your pan with the lockouts? Will your pan clear his cart? Does he have an electric water pump for your motor? Will your big oil system allow room to hook up to his cart? Oil pressure hookup is simple. Do you have a source for manifold vacuum? He probably has a Morse cable for throttle. Do you have the right size ball stud? A bracket to mount the Morse cable? Is your distributor compatible with his boxes? Need to bring your coil? Will your plug wires clear his dyno headers? Fuel hook up? It's easy to say that he has everything. Sure about that? Are mopar his bread and butter? Probably not. It's pretty frustrating when one item stops the whole show.
