Just measured the bores on a 400,000 mile LQ4 & was close to PERFECT, It is getting a 4" stoke crank & will only need to be Honed a few thousands with new standard bore forged pistons which are actually a little oversized!

Comp Cams is a JOKE, Call Cam Motion for a custom grind which are A LOT easier on valvetrian components including the lifters. I build all my LSX engines with LS7 lifters.
I just read your post again. Can you explain what would be a benefit with staying with the stock bore and doing a stoker crank? I am trying to learn.

Thanks
