Are there any real problems with filling a block to the freeze plugs once machine work is done as long as you torque down the mains and heads before you fill it? The motor is going to be about a 450 hp 428 that will be daily driven. I'm asking because my block is all ready rough bored .026" and possibly finish honed by now. I don't "have" to have it filled, but it would be nice to keep everything solid and drop my water temp a little bit too.
