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

Im not sure. i dont have the motor together yet. if i had to guess id say around 10 to 1? It has stock 350 pistons and 64cc combustion chambers.

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!

I use the lunati voodoo 60103 in my 79Z and it hauls azz.I had to go with a 750 carb for the upper RPM's.

I agree get the 60103 for your auto car,Im running the 60104 with my 4speed and 373's and its very streetable but I wouldn't go any bigger.I would guess about 5-10 more hp on the top end then my current 280 magnum cam.Power brakes are moderate/borderline.You'll be very happy with the 60103 good luck.

I would stick with the 60103 if its a daily driver. The voodoo 60104 and up starts to get into more of a race profile, not too mention the vacum loss! I think the 60103 would give you better street manners.

Gross Valve Lift (Int/Exh): .468/.489

RPM Range: 1400-5800I didn't realize the .050 numbers were so high on the 60103 (not paying attention:screwup: ), so I'd have to agree here. I think Shane73Z runs the Hyd. roller version of the 60102 in his 406, actually.

This is why I mentioned the old Isky 264 Mega hy-cam. That and being right around 9.5 to 1 CR'd.

Imho, it will be POWERFUL!

Note! Nothing fancy, but it will flat cook!
