What do you think of this cam.... 222/224 .576/.551 @ 114
How would this cam do with very mildly ported heads that flowed (MN6 LS1):
Lift Intake CFM Exhaust CFM
0.100 59.8 52.2
0.200 124.0 112.5
0.300 188.2 158.3
0.400 239.3 199.0
0.500 265.3 224.7
0.550 275.2 231.8
0.600 282.0 235.9
All the bolt ons, also. Not my car, a buddy's <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: What do you think of this cam.... Why the 222/224 duration and .576/.551 lift? What's the reasoning behind the spec's? What ramps?
It's generally my understanding with LT headers our cars are far more intake restricted than exhaust restricted.
I'd favor a TR-224 over that cam your friend selected. The flow on the heads appears to be prety much peaked out a .550 as they only gain 7 cfm more at .600. I don't think the .576 lift will really get you anything over a .563 or whatever the TR cam is. I think the TR would make a little more power due to more intake duration and idle a little better being a single pattern. If the ramp speed was the same the TR might be a little easy due to slightly lower lift on the valve springs.
I'd also favor a varation of the Hammer cam over what's listed too.
Let's see what the others think...
