    Can anyone tell me the Gross Cam Lift/Rocker Ratio on a stock 96' 5.7 ?
    From what i've read stock lift can't exceed . 425" , is that with stock 1.50 Rocker Arms before spring coils bind ? Also I've heard the Computer is not set up for much more than a stock ratio/lift with out going on the "fritz" , needing reprogramming .
    I read that Crane/ Comp Cams have a tool that cuts the spring seats wider, and cuts the Valve Stem Boss for the after market seals (can't remember if it was cut to .531") .
    Hope this makes sense .

    Thanks ,
