Hello  I have a almost perfect std. 312 crank. Number 1 rod throw is worn on inside. I doubt a .015 cut will clean it up. I have read on this forum about offset grinding.I also have a set of  .040 cast pistons and rings I would like to use. Scat makes a 6.2 inch H style rod 2-350-6200 with a bushed small end. If I added right should give close to zero deck height. BUT looks as thought i would have to press scruby size bushing 9.855x927x1.066  out. Press in a Scat B912 (assuming it is 9.855x.907x1.306) bushing. Surface big end width .940 down to .876 and trim bushing lenght back to rods small ends width. I have read you can buy a narrower 2 inch bearing (scruby) insert although I don't know if it will work. Will I have interference problems or is there a reason this will not work?  I know there is a lot of buts and ifs here. Thanks for any advice.
