More than one advance curve for 427?!?

By Josh Carroll - 04/06/2001 1:52:13 PM; IP 131.238.12.217

Dave,

Thank you for taking the time to look that up for me. I am a little confused because I found a ford high performance book last night at the book store that spelled out the following advance curve for the dual point centrifical advance 427 distributor. 12 degrees initial

250rpm = 0 degrees
500rpm = 4.5 degrees
1000rpm = 10.5 derees
1500rpm = 12.5 degrees
2000rpm = 14.5 degrees

and a total of 38 degrees. Is there more than one advance curve for a 390HP cam / stock 427 cam? Anyone else have any thoughts or advice? The book I looked at also did not spec out the whole curve because they stopped at 2000rpm = 14.5 + initial = 12.
That adds up to 26.5 degrees and they call for a total of 38 degrees? Again, any help is more than appreciated at this point!

This thread, so far...
