    No cross breeding. I work for a chevy dealer here in Des Moines and could get a good deal on one. But I dont think the LSX block is all that! There are LS2 with sleeve kits in them that will handle way more power!

    from what i've read truck irons lq motors are a good upgrade from the ls1, ls2, ls3 because they all flex. and the lsx is a lot stronger then the truck iron blocks. would make sense since the truck iron's are 80lb's heavier then the aluminum blocks and the lsx is 80lbs heavier the the truck iron blocks. I'm sure they wouldn't add the weight for no good reason.

    Problem is people bore the lsx too much for big boost sometimes. Keep it under 400ci and the stroke down to 4" or less and everything will be better off.

    Ryan, you know better than to bring cross breeding up Sounds like a sweet setup though. No more 10.5 I take it?

    -Small bores seal easier due to less area with the same amount of head bolts
    -bore integrity is improved with extra material
    -long strokes move the pin closer to the ring pack reducing space and limiting how far down the top ring can be
    -long stroke pulls the piston out further at BDC

    There has been some instances of large bore lsx cracking In large bore boosted apps as a result of core shift in manufacturing. I should have said 427 or less as it's still pretty thick and safe (4.125 X 4"), but I'd sonic check it. The long sleeve of custom ls block is better for long strokes (erl, etc) but the piston still gets thin. GM should have made the lsx sleeve a little longer (it's longer than stock, but not much). lsx is ~ the same deck height as a normal ls block unless you get the tall deck which isn't what a gmpp 454 is. Most big lsx shops would not want to run a 454 lsx under big boost.

    Anyway, is the car going not going to run the 10.5 stuff anymore I take it? Sounds like a cool build.
