    I'm still trying to pick a cam for my 80. I'm down to 2 cams the lunati voodoo 60103 and 60104. I just cant decide.:confused: lol Which one do u think I should use? I have a 350 with canfield aluminum heads (195cc runners, 202 valves, and 64cc chambers), edelbrock performer manifold, edelbrock 600cfm carb, hooker super comp headers, th350 trans, 3:42 gears, and Im probley gonna use around a 2800 stall converter. My cars a driver that will occasionally see a little track time. I don't wanna get horrible gas mileage but i wanna get the most out of my motor. I'm kinda leanin toward the 60104 but idk if that will be to big for my application? What do u guys think? thanks

    Alrighty then......I have a 383 flat top ,high lift Vortecs, 10.5 to 1, 4 speed 3:73 UDHarold told me to go with the Voodoo 104...I wimped out and went with the 103. This cam idles at like 14-15 in of vacuum, notice the idle but not choppy or anything...I should have went with the 104, AND still might change it. I say do the 104.>>>>>>>>>>>>>>>>Ken

    If you do have the stock dish pistons in there you are at 9.3 or 9.5 to 1...and that means use the #103 Voodoo.

    Go smaller. You won't miss the 10hp, but if you go too big, you'll miss the driving manners of the smaller cam.

    It's NOT SOTA and certainly NOT a UDHarold cam, but, imho, the old Isky 264 Mega is made for a 9.3 to 9.5 CR. engine!

    It will be powerful!

    You get her up to 10 to 1 CR., then install a 268 VooDoo!


    PS., and I'm a UDHarold fan!
