Lift question Would it be beneficial to go with a high duration cam but still keep the lift low and also have a tight lsa to keep midrange power at its best? For example, wouldn't a 224/224 .563/.563 110+0 make more under the curve power and still be able to make good peak power better than a 224/224 .588/.588 112+0? I would think that the 110 and low lift would suit stock heads better and the 112 higher lift would be better suited for ported heads or at least better flowing heads. Am I wrong here?

I am thinking the same as you on this. My cam is a 228/230 but has a lower lift than most 228 cams. 571/573 is the lift on mine. I am also running the stock heads. Lower lift is also easier on springs. Alot of guys think of only one thing, MAX POWER but I wanted reliability also. I also probably went overkill on my springs but I got the Patriot Golds because they are good for 650 lift. I think it's a bad idea to push a spring toward it's max.

The reason that lift is important is most heads flow more at higher lift values, especially LS1 heads, even stock ones. It'd be better to have a cam with lower duration and HIGHER lift with a tighter LSA. Check out Patrick G's torque cam thread. You'll get a lot of info from that. You can't just look at LSA, either. You need to look at overlap. A 204/208 @.050 cam on a 108 LSA will have less overlap than a 234/238 @.050 on a 114LSA. Every aspect of a cam has to be designed together.
