CSX427 the dyno software will only print so many items on each sheet or so many readings per sheet. If you will call me at 870-246-7460 I will pull any of the things you want to know in the computer for you.
The reason for the 32 degrees on the cup style engine is that they have a much more effeceint chamber and plug location. The Yates heads only like about 30 degrees timing as well as the Ford Racing N-351 heads. I did not design the FE 427 chamber, they were run the way they cam from Edelbrock with the stock chamber and plug location. The camshaft design, where it is installed in the engine, head flow as well as wet flow in the chamber will affect the timing and most of the FEs we do will run b etween 38 and 42 degrees timing depending on the chamber size and the other things I listed. Take a factory open chamber 351C head, it will like about 46 degrees with this kind of compression. Take the timing from 38 to 46 and you will pick up about 30 HP or .2 in the quarter.
The air temp was about 85 if I remember right and I will have to check on the vapor pressure. The VE was so high because of the air flow through the carburetor for a 428C.I engine. I believe this 940cfm at about 7200rpms. Have any other questions feel free to call or I can give you some references that have used our dyno and they can tell you about their ets, its that simple.
Like I said before we did this deal there will be those that don't believe, don't care and don't know. Keith
