LS2/402 vs. L92/416 vs. LSX/434 Im looking at building one for a MP122HH or a TVS2300(kit pending) and run it in the 15~20 psi range.. I want to stay with a 4" stroke, thats why I have chose these combos..
Thanks in advance for your input...

Here's a combination close to what you're looking for.
950 HP Blown LSX DYNO
It's a pair of L92 heads on a 434ci engine with a TVS2300. The cam was mild. Somewhere in the 230º range. The TVS blowers are good for about 950fwhp give or take a few. Kenny did say the boost was trailing off above 6000. Still an impressive combo especially the torque at 2500
The Mag 122HH or the TVS blowers will make a lot of torque early in the rpm band and will be an excellent choice in a heavy vehicle.
Good luck,
Richard

Is there any advantage (or dis-advantage) by go to an iron block..? What would the weight difference be, 120-lbs..?
I really want to get this project going asap, thanks for the feedback..

depending on several things you can make more power with less psi. and you'll make even more with the same amount of psi. psi is the resistance to air flow. so if you have alright flowing heads, intake, exhaust you'll have to have something like 16 psi compared to great flowing ones at like 12 psi. not exact science how I explained it but you get the idea.

Personally i would go with the LS2 @ a bore of 4.00-4.02 because the walls are thicker than the L92 @ a bore of 4.070, and the LSX i about 109 pounds more than the LS2 and you can make about the same power with a 402.
Go to the site sponser called ExoticPerformancePlus.com and check out project cars and "Bob Johnsons 05 CTS-V/LS2 402 w/ATI ProCharger F-1A" they made 809rwhp @ 14.4# and thats on pump gas. i know thats not what your looking for but its a start...

Actually you are both arguing about something that is totally irrelevant if you don't have the money to pay for FI or larger displacement. Therefore I believe there is no replacement for the cubic inch dollar. Mabe we should start rating engines in cubic inch dollars. lol
