I am putting together the parts to do my first modular build in my 07 gt500. I am intending to have a local machine shop who does a lot of modular stuff do all the machine work i need on my original 20k mile iorn block. My question is to those who have built their iorn block, what bore size were you able to achieve with the block? My research tells me .030 over on a 5.4 iorn block is pretty much the max bore without sleeves. I would like to do as little boring or honing as possible to try and keep as much strength as possible. I know every block will be slightly different..... but what did you guys wind up getting away with on your blocks. Thanks in advance, chad
