cam lift with roller rockers

[DANNY8]

Not sure exactly how to work this out. I've got a 284 cam which has .480" lift, calculated with 1.6 ratio rockers. What lift will it be if using 1.65 ratio rockers?

If I've worked it out right it's .495".....does that sound right? All I done was divided .480 by 1.6, which is .300, then multiplied by 1.65. Is that how it's done?

yep, you got it in one.
