This was still going on in the early 1980 as I was involved with a program that they called Stock Engines, Ford would buy cars from GM, Chrysler and other manufactures run Performance, Fuel Econmy, NVH and Emission Tests then pull engines out of vehicles run them on Dynod then send to Engine Build-Up dissamble and measure them. Then puld a report on each vehicle.

That is true of pre 1972 cars Ralph, but after that they were "net" with everything installed as today. I used mostly mid 70's cars for that reason.

Regardless of how, or who done what, potential is what a class racers is after.
If eng A is rated at 99% of it's potential, who going to try it? Nobody.
If eng B is rated at 50% of it's potential, everybody will consider it....unless it's hidden, then only Billy Nees or Bob Shaw will find/try it! LOL!

So the only real question is then, what is the true potential of the new motors?
Then, can they be factored the way the old motors were?
In other words;
A is 400hp@ 80% = 500hp 100%
B is 400hp@40% = 1000hp 100%

If both engines start out at .58 factor, one will obviously cause a ruckus.(as we have seen with turbo or supercharged engines)
So, do you rate older or N/A engines at .58 to start and pressurised eng 1.1 to start?
What is a fair place to start pressure engines? Maybe starting them at 1.3hp/cu.in IS fair?[/QUOTE]
