    QTY
    20080721 - Lunati Voodoo Hydraulic Roller Camshafts is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Basically it's a LT4 Hot cam with 1.6 lifters. Look at the LT4 Hot Cam specs side by side with the Lunati and this cam does what the LT4 does with 1.6 rockers but using 1.5 rockers. I guess you could up your game and run 1.6s. Buy this cam and take the $250 you save over the Hot Cam and go get some good roller rockers. If you have an L-31 with a 880 roller block this cam will work with LS-7 roller lifters I'm running Morels with AFR heads and if running guide plates get good hardned push rods too and run Chevy 10105117 .028" or head gaskets and bump your compresion and quench up or Fel-Pro .015" Head Gaskets 1094 for even more compression.
