Advertised Duration (Int/Exh): 268/276

LSA/ICL: 110/106
Valve Lash (Int/Exh): Hyd/Hyd

Needs more cam. That's gonna ping it's self to death.

64cc head, flat top 383 is in the 10.25 to 11:1 compression range depending on head gaskets, deck height, and piston CC.

I would say you need at least 10 more degrees duration @ .050 on both intake and exhaust.

Also why such big heads and such low lift? Those heads really shine at .600" lift.. Get lift up to at least .540, .550 range.

I have this cam in a .040 over 350 with aluminum 190cc heads with 10-1 compression. It runs like a bat out of hell for what it is. Given the extra stroke you have with the 383, yours should run even better. In fact, if you haven't bought yours yet and depending on your gears, you might even consider going up one step to the 104 voodoo cam. Either way I think you'll be very pleased.

Heads are way to large for application... I would get with Chris Straub @ Straub Technologies to have him grind you something that will take advantage of what you got. Typically for what your building a 195cc head is as big as you want to go.

What kind of flow do you have on your heads and what work is done to them.

ok that cam operates in the 1800 to 6200 range n the intake i got operates in the 1500- 6500 i chose it cuz i figured b best to match them close as possible if i go bigger the ranges on the cams start at 2200 so what lunati voodoo cams would u guys pik for my application for the street wit the intake n heads i got ????
cam needs to b a hydraulic flat tappet no money for the high dollar rollers give me some cam numbers to look at online plz

Agree with this. Without knowing all the specs on your engine it's a little hard to say what your compression is but with the flattops in a 383 it will most likely be in the high 10's for compression. Your going to want to be spot on with the cam selection or ping ping ping.
And more than likely the cam will be getting bigger. Which then you may need more stall out of your convertor.

Agree with above posts about pinging. With those heads (little big for intended purpose) for sure the 60104 or even 60105 and at least a 3500 converter. Otherwise you're going to either ping or have a dog on your hands.
