[QUOTE="birdman941, post: 9360774, member: 29150"] I found somewhere that the Aussie Boss 290 uses 2000 "R" camshafts. Not 100% positive, maybe someone can chime in here. If so, here are some specs and (looks like engineering) numbers: Intake Camshaft RH-(8912 6A270 AA) LH-(8912 6A271 AA) Intake Opens @ 13.4 Deg BTDC Intake Closes @ 65 Deg BTDC Intake Opening: 2.54mm Lift @ 18.9 Deg ATDC Intake Closing: 2.54mm Lift @ 30 Deg ABDC Max. Lobe Lift = 7.18969 mm @ 113.8 Deg ATDC {13mm at Valve} Exhaust Camshaft RH-(8912 6A272 AA) LH-(8912 6A273 AA) Exhaust Opens @ 59.7 Deg BBDC Exhaust Closes @ 17.9 Deg ATDC Valve Lift 2.54mm Lift @ 27 Deg BBDC for Exhaust Opening Valve Lift 2.54mm Lift @ 17.1 Deg ABDC for Exhaust Closing [/QUOTE]
