Block weight is roughly 80-90 pounds difference. Other things can change that obviously.
Stay away from the Eagle cranks. Not happy with mine...may go with something else if I ever get around to doing the turbo build I want.
It all depends on what your goals are. 40x may not be needed.2008 Trailblazer SS

80-90 lbs right now is not that much......but that being said over the winter when I switch out the k member and finish the rest of my car's diet that 80-90 lbs will seem like a lot.
With spending way too much time researching I am really leaning towards the ls2 and stroking it to a 402

personally i like the aluminum blocks for a few reasons..1. it is lighter...you could always do a k member swap and get that weight back down..but imagine a aluminum block and then doing the k member swap.. you then have the same power as the iron block..but running 65 pounds or such off the noise. 2. The lsX aluminum blocks hold power extremely well..i dont see you in the 1000+ range...so durability isnt really that big of a issue.
i am with firebird on the l92 heads...they are not that impressive really..i have herd the big issue with them is the fact that they have oversized valves and that is causing some flow characteristics. On top of that..i know TFS is coming out with there rectangular head set up for the ls3-ls9 crowd ..
i say if you are going n/a with some giggle juice...why not go aluminum alloy ....it isnt your grandfather's aluminum block..these genIVs are solid solid solid blocks...the only thing they have against them is their think sleeves ...hone and done as they say.
so i say a stock ls3 ...pop a fast 102lsxr..get some head by this time there should be a stronger showing in the aftermarket casted heads ...and get a real cam and not have to worry about the strangeness that the l92 heads play on cam selection.
