Hey man, what aluminum block do you have? Fastest stock sleeve and block LS here in the states is an aluminum LC9 block. Look up "Nigel STST" on here he has gone low 4's at 169 in the 1/8th with his stock aluminum block. I think you should be fine with yours.
That's insane fast 👌 I'm using a 2008 ve 6 litre block, with some grout and a crank girtle we would get a bit further but cost is about the same so decided on the ly6 block, and that leaves me with the alloy block and crank (also upgrading the crank) to use in the ute if the 5.7 should happen to let go
