I know this gets asked alot but I cannot decide my self which one to use. Fist I want to tell you about my set up. I am running a 350ci engine with Summit brand Vortec heads (175cc intake, 67cc combustion chamber), Weiand Vortec Street Warrior intake manifold, my TBI unit flows 620 CFM, 9 to 1 static compression, 1 5/8" headers with 2.5" collectors flow into a single 3" exhaust, 1800 RPM stall converter w/ lock up, 4L60E trans thats been modifications, 3.42 rear end gearing, and finally its going into a '94 Chevy K1500. Low end torque is important and I would also like to get decent fuel milage as well. I have 2 Lunati flat tapet Hyd. cams first one is an older single pattern grind from them that specs out to 268 ADV/218 @.050, 110 degrees LSA, and .457" of lift. The second one is a Voodoo cam that specs out to 256/262 ADV Dur, 213/219 @.050, .454/.468" of lift on a 112 deg LSA. I will be using a set of Lunati 1.5 full roller rockers on which ever cam is picked. I also purchased the recomended Lunati springs (same springs for both cams) for the build. I am leaning twards the Voodoo my self, but I am willing to use which everone comes out on top. Thanks

if limited to only those two the lower intake duration and wider LSA of the voodoo cam seems the better choice

Looking at flow numbers, I'd also pick the 213/219 camshaft.

Where did you find flow #s for the heads? I have been looking and all I have is a very basic # from summit.

Instructions sheet. Be sure these are the same heads.

Or you can spend about $50 to have the heads flow checked somewhere locally. Atleast that's what it costs here in Louisiana to flow check 1 cylinder and both intake and exhaust.

Thanks for the info. They must have added that spec sheet not too long ago.
