Default Low end torque on "big" cams?

I have heard that "bigger" cams, i.e. 224° and higher, will have less low end torque than a "smaller" cam. But, will a 224°/228° cam still have more low-end than the STOCK cam??? It seems it will.
What do you think?

midsized cam verses a larger cam (the sheet says 224/224 but it was actually 230/230)

So, the 230°/230° didn't make much more power than the 218°??? <img src="gr_eek2.gif" border="0"> Wierd.
I am wanting a 224°/228° one day on a 112°LSA.
I just hope that will have a bit more torque than the stock cam.
Thanks. <img src="graemlins/formula.gif" border="0" alt="[Pontiac]" />

One thing to watch for here is the displacement. I have heard from several sources that going beyond 222/222 on a stock cubed LS1 does not get you anything and just only kills idle. On the other hand, a bigger-cubed LS1 (stroked, big bore, etc.) is a different story.

I wonder how JMX's dyno graph would look if both cams had the same LSA.

I will be staying with the stock 346" for a long time. jhelms has a 224°/224° .581"(?) in his car and loves it.
I also am curious about the LSA on jmx's dyno.
I also noticed the 230° cam had a lot more lift, were the heads modified to take advantage of the higher lift??
Maybe a 222°/226° would be better for me as far as torque goes?? <img src="images/icons/confused.gif" border="0">
