I've been looking around for some opinions on this cam on various sites and it doesnt seem like many ppl have discussed the voodoo cams much. The specs on this cam are as follows:

Advertised Duration IN/EX: 270/278
Duration @ .050 IN/EX: 221/229
Gross Valve Lift IN/EX: .515/.530
LSA / ICL: 112/106
RPM Range: 1800-5800

My car has an Edge 3000 stall converter, 3.73 gears, CAI & catback exhaust. It still has the stock manifolds and cat converter on it and I dont plan to change this anytime soon.

Has anyone used this cam or known anyone who has? I'm curious how it sounds and how well it does in the low/mid range power band.

specs are pretty close to the hotcam, slighly more duration. I think it'll work well for ya, but consider a bigger stall in the future. Also make sure to get a dynotune

i believe that cam actually peaks at like 6200 IIRC, i called lunati once and asked about it, but i decided to go w/ a LPE cam. That cam will work nice too. Are those lift #'s with 1.5s or 1.6s, i believe those are w/ 1.5's, correct?

stereomandan

High lift, low duration. Great street cam. Those numbers are with 1.5 RR's correct?

Make sure you get good springs that can handle that lobe.

I agree. Has anyone looked at the springs that lunati recommends with those cams? They seem pretty weak for the lobes.

Thanks for the responses yeah the lift #'s are for 1.5rr's

I agree that those springs do look a bit weak, but thats what they recomend. I was going to get the comp 918's but after reading about their problems the last few months I think I'll pass. If lunati recomends these springs then I hope they're good enough for lifters though, I ordered the comp 850's.

I'de go with the pac 1218's or 1518's. I'm not sure if Harron is still doing the GP on them, if they aren't SDPC on ls1tech has the 1218's for $120.

Just bought the PAC 1518's from Shon through the GP for $220 shipped. From what I've read, these are the way to go.

How this cam would compare to the cc503 in terms of:

-Power/Torque?
-Lope?

seawolf06

I didn't notice it before, but your numbers are off a bit on the cam specs.

As far as comparison to the 503:
Overlap/IVC
503 54.5/66
60121 50/61

The Lunati cam has less overlap and an earlier IVC. I believe this means that it would work better with stock motors as it provides higher DCR. Not sure if that's a great thing or not, considering the very high quench that the stock LT1 has. Generally, with more overlap you get more hp in upper rpm, but at the loss of lower end torque, IIRC.

The Lunati cam also has 6 degrees of advance ground into the cam, instead of 4 degrees like the 503 and most other LT1 cams. I think it all means that the Voodoo cam would be more of a torque monster, but may not have the punch of the 503 at higher rpm. Don't know until you try it!

Here's a dyno of mine:unported heads and TH350 unlocked converter

seawolf06

gex598 - GET YOUR HEADS PORTED! lol, how do you afford to build a 383 with a th350 conversion and not get your heads ported???!!!

camaro81

eh that torque looks kinda low man, my stock LT1 with just a tune, CAI and SLP catback exhaust made 347ft lbs of torque and thats thru the stock manifolds and cat converter.

I just ordered a scat 383 rotating assembly and I'll cry if my setup dyno's below what my stock LT1 did even if the hp is much higher

From what I've read, Bret Bauer is a great person to go to for a custom cam, expecially with an oddball setup. So since I'll still be using stock heads and manifolds, I may check out his prices instead of going with a Lunati cam.

gex598

Yup your dyno put down more torque but look at where it did that. By 4000rpms your already below 300ftlbs and droping fast. Im sure if my converter didnt flash so high I would of had a much higher torque output as well. The other looks like you sprayed it. Its not about peak numbers, its all about the curve, and useable power. I bought the T/A blown up, I built the motor and had the tranny. Total cost to build the motor including springs, cam, rockers and bottom end was less then $1800.

camaro81

Yeah my mouth must have kicked in before my brain did, I just saw the lower numbers and after spending as much as I did on a 383 I got worried My car with the stock motor had absolutely no ***** from a roll, but it would launch hard as hell. Hopefully with the new motor it'll feel better throughout the rpm range.
