Personally I think dyno's are for people who either don't know a damn thing or people know way too much. I've got hundreds of Dyno sheets on my motor all of them are about a foot long and 3 in wide and not one of them tells a lie.
My "Dyno" is a 73 Duster! I would be more than glad to LOL put anybody's motor on my Dino, Run it in for 20 minutes and then give it a time slip that will be 100% guaranteed accurate horsepower reading.
Edit: I'll be having a half-price sale for the rest of the year! LOL

This statement assumes that everything for your particular car is optimized for the combo. Converter, gear, shocks, chassis stiffness, etc. To make a fair and accurate comparison you would have to optimize all of those for each combo. Just changing rear gear ratio will change that substantially on a chassis dyno. You can give 6 people identical wedges that made 700hp on the same engine dyno on the same day and have 6 vastly different timeslips at the track depending on their experience.
