From what I have heard the range is like 640 to 660 lift.

We have run upwards of .685" lift on OEM rocker arms and trunions. That being said, it really depends more on your lifter/spring combo as to what lift the valvetrain can handle. If we can assist with any camshafts or valvetrain components please let me know and I'll be happy to help!
