If you are going to be under 3.850 stroke it will be ok. I would not recommend over 4.00 ( LA standard sleeve ) for 4.00 and up stroke. The piston side load is a know problem for 4.125 strokes, A thinner liner will only make it worse. Back when I was working on a 368, I called the top 4 builders. All of them said ok up to 4.030 bore for a 368 ( stock crank ) All said no for a 415 ( 4.125 stroke ).
