BlownBuick is on a distinguished road

With the power your looking at putting out, you'll need to replace the stock internals anyway, so I would imagine that you could make any engine as powerful as you wanted. I think 1500 hp is about as much as you could expect from either engine. I think that I remember reading somewhere that at around 1400-1500 hp, the heads on an LSx series engine actually start to lift off the block because the head isn't held on with enough clamping force to withstand that much power.

Another question, do you expect to send 600+ hp through the front wheels?

h0ckey4: i could strap supercharger to the LS7
xsC: not quite
xsC: you'll blow it up
xsC: and on top of it, you won't get much of a gain
xsC: since you'll need to find someway to de-tune it and then blow it
xsC: compression ratio is too high for the ls7
xsC: and it has thin sidewalls for the cylinders
h0ckey4: how would a supercharger blow it up?
xsC: too much pressure for the cylinders to handle
Well, it is true that you'd need to lower the compression ratio to use any kind of forced induction set-up on an LS7, but I don't imagine how you could manage to crack the clynder walls. They're not that thin. Lingenfelter can get 800 hp out of an LS7, I don't know why you shouldn't be able to do the same.
