Ok, I talked to a cool sales rep & also a tech at Lunati about the best Voodoo cam for my 71 W100's new 383. The block was decked & forged pistons are .018 above the deck. Stock 440 Source heads (80cc) w/ single springs , headers, Weiand dual plane intake, maybe Holley vacuum 750 or Eddy AFB, big tires (33x12.5x 16.5) and 3.55 gears (soon changed to a 518 w/ 3.91's or 4.10's with OD).. Might tow once in a while open car trailer, etc. The tech says the 703 cam with a 114 Lobe sep is better than the 112 lobe sep 702.
Would sure appreciate your info on which is best & here's the specs:
