Andy,
I have a 700CFM 4di on a '70 Ford 302 with a farily hot hydraulic roller 
cam, .520 lift 224 @ .050 and 9:1 compression.  I use all the advance 
without a problem.  It took a lot of playing around to keep it from 
backfiring during warmup and to pass emmissions at idle.  The map 
provided with my unit for the 302 looks nothing like what I ended up 
with.  There is a projection web site that might help you out:  
http://www.genevaonline.com/~efi/.  I have sent my maps there for 
reference.  me

Does anybody have any suggestions for ignition timing on a 454 with 
digital projection?  Performer intake, tube headers, 268 cam, etc ,etc. 
I can vary my ignition advance from 0 to 48 degrees with the ECU.  I 
guess i am wondering what it should be at cruise and full-throttle.  I 
have heard that a big-block chevy should be able to take 40 degrees, but 
that sounds high.  thanks!
