ARE preferred that we did not show their proprietary methods for installing and sealing the new cylinder sleeves. After all, it's this step that has kept everyone from doing it. Once installed, they can be bored like a standard engine block. Consider this, friends: If you don't have the dough for a complete ARE engine or think you can tackle it in-house, consider paying these guys for this service alone! Final honing is performed with a torque plate. While the bore could be as large as 4.125, ARE machined the bores to 4.1 inches, as Agostino elected to leave some material for future clean-up. After line honing, the block was ready for assembly.
