Safe to bore a 383 60 over?

Never heard of that! Well, it's getting picked up from the machine shop on Fri. It's 60 over now with new pistons, block sonic checked, crank cut to 20 under, cam bearings r&r, hot tanked, rods resized with high strength bolts, all bearings and rings included from the machine shop. Quick turnaround. Looks like I'll have boat anchors lying around in the form of 40 over pistons...lol.
I'll update this weekend.
Oh yeah that's quick turnaround. I wouldn't even worry about it being.060, just run it like she's brand new and have fun.
