The lunati was 247/253 @.050, .540/.550 lift range. I wouldnt drop the lobe centers past 108, and icl ahead any more than 102-104.
Will start getting real peaky, have flat spots and wont perform well in upper rpm.
This is just what i learned when i was playing with slants. (that, and dont go over 30% nitromethane)
CharlieS, slantzilla, and perhaps slantcecil can shed some light for you if ya catch them in the rite mood.
