He only mentioned ONE part---an original crank!!!
The dynoes are set up for a test range and the operator ran the car to that MAX SPEED ---I don't know what type of dyno this was on but probably a Mustang?
AND----you do want to run it past MAX power so you can compare hp/tq curves to determine shift point according to gear ratio spread---
If this 289 had an original crank, what did it have for rods, bearings(and size)
oil system, and was it a 4 bolt main?
