I think the LS7 block is designed to be stronger as it was built for racing use. The L92 block was designed for production vehicles. I think the L92 should be fine for most folks. If your going to constantly turn it to 7K+ rpm in a LeMan type track, then go with the LS7 block.
Hopefully someone with more info can post up.
Oh yea, I think the L92 uses a different deck angle so LS1 based heads won't fit. The LS7 uses the standard LS1 angles and heads.

Not to bash the setup its good for the money and I know the flow # are there but the powers not, in the 2 motors that I put together at my job (408w/L92/l76 ) I have seen the same #'s from an ls2 with TFS heads . Obviously the big motor made more down low .
