I run 10.2:1 compression on my 360 with the stock cast crank and stock rods with good arp fasteners through out (main studs and rod bolts, arp pro wave 2000 for the rod bolts), with polished beam rods. Pistons are wiseco pro-tru series. Have over 200 passes on 150 shot of nitrous (440 whp) without issue. I did have it fully balanced when I was putting the engine together though. Hope that helps!
