Just remember...a dyno and the numbers it produces has limitations just like any other tool.
So two cams and appear similar and make the same or similar power curves can and will behave differently in the car. That’s why cam selection isn’t splitting hairs. A custom ground cam will always produce results that can’t be measured on a dyno.
Larry Morgan wrote in an article way back in the late 90’s that he spent the entire offseason testing only cams. He went through a drum of fuel doing it, which is huge amount of dyno pulls.
I’d bet you could lay the vast majority of the power curves over each other and it would look like the same line. Yet at some point, they had a decision to make as to which cam with their engine was the one to test in the car.
The point is cam timing is critical if you want the best power, driveablity and overall performance. Things like how well the engine recovers RPM off the Transbrake or off the pedal and how well it it recovers RPM in the gear changes. The more gear changes, the more critical that aspect of cam time becomes.
