I was always taught that duration was more important than lift
Basically - High duration = more top end power, lower duration cams give more low down torque and a better idle.
You can only physically get so much lift with shorter duration cams, lift is a function of the "rate of lift" that the lifter itself can cope with.
I have to run a solid lifter conversion on mine with the 280 cams, the standard hydraulic lifters can't produce the lift of anything over a 264 or something.
Also worth noting that different cam manufacturers will quote lift at different points on the cam lobe as a function of lift, so if you're looking at a few different ones make sure it's at the same point
