The MOPAR/AMC lifters that I use by sleeving down the stovebolt block are .904"- - - - -about halfway between the small block V8 and stovebolt lifters. I leave the inside diameter of the seamless steel tubing a few thousandths undersize as I press them into the block, and then finish-ream them with a 23 MM spiral flute chucking reamer in a variable speed drill motor, with the first 1/2" of the flutes ground down to be a slip fit in the slightly undersize sleeves, for alignment purposes.
