yeap u are right, but there is the catch 22 in this engine, the 4T head components are what makes this engine great, the 4t block is just a .20 over size 3t block with all the exact same internals, and the 4t stamp, so i am ohhh so cherry here, PLUS, i am going 87mm over size anyways, so from 85mm to 87mm, and eagle rods, and off course i will bring updates on this periodically!
