Will a LS1 aluminum block hold 700~750RWHP reliably on occasion, and 500~550 daily in a mid 10sec 5000LB truck? Of course that would be studded, with good pistons, and rods .003'' over bore. RPM will be below 6500, and boost 14PSI MAX. Thanks, J

Yes, the block is no issue as long as internals are speced to handle what you throw at it.
