I wish to swap camshafts in my vehicle and have been looking at Lunati's Voodoo Series cams. Here are the two cams I have narrowed it down to.

Adv Dur: 276/284
Dur@.050: 233/241
Lift: 504/525
RPM range: 2200-6400
LSA/ISL: 110/114

Adv Dur:284/292
Dur@.050: 241/249
Lift: 525/546
RPM range: 2,500-6500
LSA/ISL: 110/114

My engine specs
350 ci +.060
10.00:1 compression
TRW forged flat-top pistons with single trough relief (L-82 pistons)
Edelbrock RPM Heads (64cc) (Springs allow up to .575 lift)
Weiand Stealth Dual Plane manifold (Idle-6800 RPM)
Mighty Demon 750 cfm carb
HEI ignition
355 gears
Converter Stall Speed: 2,500 RPM
Cast crank

Which of the two cams are more closely matched with the engine internals I have? I am leaning toward the first. Looking for mid range power-up to 6500rpm (won't rev it that high but will if needed)

Suggestions are welcomed.

I would tend to agree with you on this. I ran a 248 @ .050 cam with a .525 in a 350 and it was a little soggy on the bottom end. I also had 3.70 gears and a stick. With an auto I would imagine it would be even doggier on the bottom end. The first one is going to be hairy enough with that combo.

With 10:1, auto, and 3.55's, I'd lean toward something in the 230 @ .050 range.

If you're running headers and good exhaust system with those good heads, I'm no fan of dual pattern cams.

I think you are too large on the cam, I'd drop it down a bit. Maybe something like an Engle EP-46Hyd, 277/277-230/230 @ .050 with .489" lift. Rated for 2,000-6,000 RPM power band. Maybe have it ground on a 112 LSA.

Another Voodoo Cam

Adv Dur: 268/276
Dur @.050: 227/233
Lift: 489/.504
LSA/ICL: 110/106
RPM Range: 1800-6200

Seems Closer to the power range I perfer and leaves a little (although very little) on the table with the components I have.

You just have to watch your DCR value with that 106 ICL, you are at 8.3:1.
