I just recently aquired an new 1168 LS1-6 block. After measuring my bores, I came up with 3.895 on all bores. Stock is suppose to be 3.898 but this block has somewhat shiney bores. The crosshatching is faintly visible but not like a normal finish hone. Are these blocks made this way normally so the builder can finish hone it the match factoy specs? Just curious if I could get away with a light hone with my trusty ball hone. I might trade my 3.905 pistons for for 3.898 units if I can.

 

I would not try it with a glaze buster ( ball hone ). Do it right and get it honed by a shop with a deck plate.

I've used the glaze busters on cheapo rebuilds but not on a block that I would keep for myself or garantee.

 

I agree with you. My problem is that I am in a rural area in PA. and am at least 50 miles away from any good machinists. I'm not taking it to my local NAPA, lol. Thanks for thr advise.

 

50 miles isn't that bad. Do it right the first time. You'll be happy you did in the long run.
