thats like a wife thats too hot...

tall deck....if you can afford an aluminum LSX, the intake and headers are the least of your worries.

if this happens, I will have a 500 cid N/A pump gas street car....

oh and I'm pretty sure "IF" this tall deck LSX happens, plenty of manf. will have intake and header opts.....just a hunch. You won't need custom anything, if the block comes, the trail of supporting components will always follow.

What, if any, is the potential release of an aluminum LSX block? Any news?

Tall!!!

4.25" stroke cranks are everywhere now. If you're a cheap bastard, cut a second hand GMPP LS7 4 barrel intake in half and weld it back together for an intake.

Besides is this even worth discussing? GM already sells a big bore Al block with a standard deck height, it's called the LS7.

+1, it will just take some time.

Most companies don't even charge more for the larger stroke cranks. You should be able to get a 4.25 stroke crank for the same as a 4 inch.

I agree.. Although alot of guys will say they'd want it (bigger is always better right) I think in the end, they wouldnt want to pony up the extra cash on all the supporting mods to make it work.

I will definately order an aluminum version when its released.

Is this something GM is even considering or just wishful thinking?

I agree but do keep in mind that if the stronger/beefier LSX aluminum block were to ever happen it likely would still weigh notably more than a standard aluminum LS1/LS6/LS2/LS3 block...but yes it will definitely be lighter than the iron LSX version and hopefully less than the LQ9/LQ4 blocks as well which is a good thing.

True, but that's not going to take boost/big nitrous shots quite as well as an LSX design. But for an NA application that is a great block to use, especially being lighter than what an aluminum LSX block would likely be.

Standard. If I wanted to go all out with a tall deck I'd go Warhawk anyways.

The deal maker here for GM will be the price/quality/quick delivery.

How about a different angle to Robin's question. How much would you be willing to spend on an aluminum LSX standard deck block?

All at current dealer list price:
19166454 LSX iron version - $2600.
12480030 C5R - $9360
19213580 Aluminum LS7 - $3380
12584727 LS3/L92 - $1822
12568950 LS2 - $1392

Blocks currently available in the 2008 GMPP catalog

LIST price. You can always do better than list if you look around. Big wholesalers will always sell them a lot less. List price is the only common price you can put on a part, its up to the dealer as to what they want to actually sell it for.
