A 40-60K mile Ls1 is just broken in!
They can be had for about $3k turn key, and are about 400 hp at the crank in stock condition.
Really, to each there own, it all depends on what you want, goals, and what you will be happy with. I tell you though, I have not talked to one single LS1 person that has any regrets or complaints from the swap. If you already have a sbc, then keep it, but if you want fuel injection and an all aluminum lightweight motor and or have no motor yet, you might consider the swap.
