CAM HELP NEEDED!

I maybe miss understanding you on this so don't take it the wrong way. RV- torque cams have short duration and more lift. Example: .479 / .494 x 255* / 261*. That cam has almost a half inch of lift while it has a short duration. Again, I may have misunderstood you
The OP seems to want to run less duration then originally recommend, and I was just saying that generally gonna come with less lift.

I don't know if so called RV cams come with more lift for a given mild duration, Far as I understand it's generally used for slang for mild cams.
