Voodoo Cam
Has anyone tried this cam?
Part # LUN-60101LK
Product Line: Lunati Voodoo Cam and Lifter Kits
Cam Style: Hydraulic flat tappet
Basic Operating RPM Range: 1,000-5,500
Duration at 050 inch Lift: 213 int./219 exh.
Valve Lift with Factory Rocker Arm Ratio: 0.454 int./0.468 exh. lift
Lobe Separation (degrees): 112
Intake Valve Lash: 0.000 in.
Exhaust Valve Lash: 0.000 in.
I'm putting in a 1970 350/300hp with 10.25 to 1 compression,3.08 posi rear

I assume that this is actual known (measured compression) and not the advertised compression on a shift console. If it's advertised compression, the actual is at least .5 points lower, around 9.75:1
IMHO, I think you need a cam with some more duration at that SCR. The inlet valve closes relatively early at 56 degrees and you have a resultant DCR of 8.6:1. DCR isn't a magic number but provides a guideline and you should shoot for around 7.5 for iron heads if you plan on using pump gas.
I can only assume you picked a low duration cam because you might have an automatic transmission and do not want to change torque converters out. If you want to run high compression and want a highly dependable street cam, the stock L-82 cam is hard to beat. Yeah it has lazier ramp rates than a Voodoo but you won’t wipe out a lobe either. It has a late closing inlet valve (75.5 degrees), and you end up with a DCR of approx 7.45:1 With its 224/224 degrees of duration on a 114 ICL, it will idle great for a stock converter too.

That seems to be a very popular grind on the car blogs, and with the right SCR and car configuration, it should perform well. I do not have any personal experience with it, however I am not a big fan of these "extreme" cams that try to emulate the ramp rates of a roller. I'd rather give up a few ponies for a more reliable valve train, at least in a street car that is driven fairly regular. If one wants faster ramp rates, go roller but at a much higher cost, its all tradeoffs, just my opinion.

I use this cam (voodoo 60101)in my `69 350/300 with 4 speed and 3.08 rear end.
Together with edelbrock rpm 64cc heads weiand actio+plus manifold and holley 600dp.
I am very happy with tis set up,god torque or hill climbing!
