744 wasn't much more intake lift than 068 ( around 408 or 410)
But had more .... whatever - duration , lobe separation , overlap , ICL , ,,,
041 was a bump stick
A lot more lift and yadda yadda
Around .450 range intake lift with 1.5 rockers , around .500 range intake lift with 1.65 rockers
Another oldie just shooting from the hip
