Anybody know where I can purchase one of these new camshafts? I can't find any info anywhere.

THANKS!

What's wrong with buying them from Lunati's???

pdq67

Just curious, but why would one want to buy a cam from a company called "Voodo"?

Do they have a witch-doctor in charge of QC or something?

Just kidding . . . have never heard of these guys though.

be sure and mix some fresh chicken blood with your cam lube! :D just joking,i have no idea who makes those,sorry.

Call Lunati, they should have all the info on this new line, it's their new subdivision.

I was under the impression that these were some of Brookshires grinds, I read on the Voodoo cams web site that they are mixing thirty years of cam design experience and mixing it with state of the art cam designs. Harolds been doing this for 30 years or so hasn't he? So is this just some kind of "Voodoo" coincedence? And besides, some of those grinds have some impressive numbers for what I want in a cam grind. Hopefully Harold B will chime in and clarify a few things!

1. Yes, Harold has something to do with the new designs at the site above

2. Harold works for Lunati

3. Lunati is now owned by Holley, hence the link above

I still want to know why most of the smaller grinds are on 112 LSA, 108 ICL. It seems the current trend is to put things on a tighther LSA and a 106 ICL to help with torque in Low CR engines.

I'm sure there are reasons for this, I just want it explained! smile.gif I've been reading stuff fromn Vizard and others that says the most toruqe will come from tighther LSAs, particularly on restricted breathing (stock-ish heads), low compression motors. These new cams go the other way.

I dynoed several of the Voodoo cams on different LSA's (same cam, just different LSA). Really didn't make that much of a difference. The tighter ones picked up bottom end torque very slightly, the larger made a bit more peak power. Not enough that a typical person would notice it. 2 degrees larger LSA picks up idle vacuum about 1". The smaller grinds are for more daily driver types that work better with more vacuum along with factory computer controlled cars.

Back to back tested them against XE cams. The XE's were pretty noisy. The Voodoo's were a lot quieter. THe Voodoo's made more power, sometimes significantly than the XE (20 HP at higher RPM with no less torque).

After dyno testing a bunch of cams I think people make a bigger deal on LSA's and ICL's than I saw on the dyno.

The main thing is to choose the "correct" grind.

These are brand new profiles, not remarketed older grinds.

Keep in mind that Visard wrote a lot of his books a few years ago and cylinder heads have come a long way recently. I'm not knocking Visard's books (good reading IMO) but maybe times and technology are changing.

I'm speaking specifically to the trend in LSAs recently. The Prostock guys seem to be leading the way for the rest of drag racing and the technology they develop seems to eventually filter its way on down to the ordinary gear head after a while.

Well, Prostockers have been using really wide LSA cams for a few years now -- I think due to the killer heads they have developed. Maybe all that extra overlap that old weaker head designs needed (Visard refers to the SBC as undervalved frequently) isn't needed with modern ports and chambers.

Could the LSA trend be headed the other way?

PS. looking at the Voodoo catalog a lot of the cams have a description includes "compatible with XXX fuel injection" which would explain the wider LSAs with this batch.

I'm no prostock engine expert but I don't think you would want to make any comarisons for their engines to a street or even race SBC. 8000-9500 RPM range with cylinder heads optimized for that combo.

I dyoed the same cam except on a 108-110-112 LSA. Judging from that data I wouldn't want to go larger than a 112 on a street car, but it didn't make much of a difference between the 3.

If you have a car like racer1320's that you are trying to get every .01 out of it, everything makes a difference. I don't think that most people really could tell, except that on the larger cams your power brakes may not work as well and you may have to tune your carb which is something most aren't too knowledgable on.

If you don't have the heads and won't spin the engine (along with having the gears, converter, and overall application), you are better off going milder.
