Take this for what it's worth: back in 2015 I found I'd wadded up a rod bearing. My motor is a 93, I believe it was 95 when they changed the rotating assembly but don't quote me. I nailed a late LT1 crank on Craigslist and had it polished. I found a set of stock takeout pistons and rods on eBay. I installed new rings and bearings, gave the bores a 3 stone hone job 320 grit with moly rings. Didn't measure a damn thing and that's the motor you saw my car run at Hallett. On a motor that needs to be restricted, perfection isn't really necessary IMO. Mine made 292whp unrestricted in 2016. I'm 1 plate size larger than I was then. Is it the book answer? No. But to an extent, good enough is good enough in our class. YMMV.
