People run half-filled blocks on the street without noticeable cooling issues or anything of the sort. Friend of mine has a half-filled bare block freshly hot tanked ready for machining for sale.

Half fill is a circle jerk. Fill it all the way or leave it alone. The peak pressure and all of the damage will happen in the top half of the bore (same place all the cooling takes place).

Is there a rule of thumb for how much n2o or boost you can run before you should start filling your block? Or is RPM more of a factor than power level?
I plan on making 800+ hp with a F1 procharger, my engine has very good components up to the task but the block is not filled...should I be worried?

i just went up to toll ( a welding store) and there was a guy there buying tig rod for cast iron. he work for 3m. and i asked him how much he would chraged to do some cast iron weld on a sbc engine fully intacked on a engine stand fliped of so he can get to them easy. he said $100 to weld them up..
would you trust him. he welds for a living. and hes done alot of cast iron.
what would you do. i do stuff the right way or dont do it. i just dont have $1300 right now to drop just on a engine block then another 800 to 1000 for the rest of the seals, studs, head gaskets so 2300 on the cheap end..
my thoughts were to just have him weld it and get it through this year and get a new block this next winter
