is it worth it to spend $1000 6.0 short block or could i spend my money more wisely and keep my stock Ls1 block?

 

If theres nothing wrong with your ls1 block, then you'd prolly be better off investing that 1000 into your aluminum block. Unless your looking into l92 heads then you may want to make the switch to the 6.0 and you could sell your ls1 block.
