It depends on the block, check with a reputable shop. A good estimate is .030 (Or 30 thousandths of an inch, in case I got the decimal wrong.)
You can't... There's not enough steel in the cylinders to bore it that far. If you want a 454, you need to by a big block 454 Chevy engine.

A "454 that is 125 over" refers to a 454 cubic inch engine (commonly a Chevrolet big block) that has been bored out 0.125 inches larger than its original bore size. The standard bore for a 454 engine is 4.00 inches, so a 125 over would result in a bore of approximately 4.125 inches. This increase in bore size typically allows for greater displacement and potentially more power, but it can also affect engine dynamics and reliability if not properly managed.
A Chevy 454 engine can be obtained when one goes to a Chevy dealer, an auto shop, or a body shop. The engine is a pretty good one as it delivers 240HP and 355 torque.
The standard fuel pressure for a 1998 Chevy 3500 with a 454 engine is 50 PSI. If fuel pressure drops much below this level, the fuel injectors will not work properly.
Many. 348 would be a small block, whereas the 454 is a big block.
