Not Ranked
Chaplin,
This is from my post on page 3 of this thread (look back there for more details):
Do something like this:
Get CR to about 10.0:1
Get hyd roller cam with ~.600 - .640 lift
Get hyd roller cam with 112-114 (wide) lobe centers
Get hyd roller cam with ~230 deg duration at .050
Cam should be assymetric - talk to cam suppliers.
I build chevys, so I would not want to make specific recommendations since Ford heads will require somewhat different assymetric profiles.
I can tell you the short duration with wade separation will give decent idle and low rpm torque characteristics (short overlap), while the big lift will still allow you to make good power.
You will need to be careful of valve/piston clearance at these lift values, but the shorter duration will help.
Keith may be hesitant to make a recommendation since he makes his living off his magic methods of getting good HP, but my numbers are pretty good generically, or he would not have had any agreement with a chevy guy.
Talk to the Cam people for specific recommendations, but give them my number as a start point and let them know you want the short duration and wide lobe center angle along with big lift in order to work with moderate compression. They will steer from there.
Good Luck
