In all seriousness let me add 2 coherent complete thoughts. #1 the iron block isn't THAT much heavier. Its like 100lbs+/- or somethin. #2 the cost is obviously going to increase the build if you go iron. The aluminum block will handle a good amount of power also. Unless you are trying to.build a 9second monster of epic destruction just save the money on the block and keep the aluminum I think.

Iron is cheaper than aluminum.
It's 110lbs heavier, but allows for better heads or more flow out of smaller bore heads. It's essentially a .1 penalty over aluminum, but for all intents and purposes, the same heads and cam will make another 15-20hp on the 6L block, so it makes up for it.
Sure, it's heavier for stopping and handling, but the engine sits so low and so far behind the front wheels, the weight shouldn't be noticeable...

There is one local with a ported head, MS3, th350 combo that is only running a few tenths faster than mine...on a 100shot.
Well, when you look at head/cam LS2s for example, they make more torque than LS1s and generally more HP out of the same cams. Usually by a good bit.
I think folks use the 6L block and use it as a cheap way to put together a **** poor combo.
Now, if I got my hands on a 6L block... I think I could make 520rwhp... Hmmm

I went through this process in 2007 when my LS1 took a crap (5 & 7 ringland, nitrous spike).
So I thought the same and got a 4.030 iron block. Well when all said and done, that extra weight was painful. Had to redo the suspension (which transferred fine when LS1), transfer the battery to the back etc...
Moral is I regret not having stayed aluminum. Now for 408+ cubes, that is antoher story.
