Possibly, but measuring the wall thickness with an ultrasonic meter is definitely recommended. You may have to measure several blocks to find one with sufficient wall thickness.
Search this forum using the term "Mexican" and you will get a number of informative threads. "boring out a 250" is one of the good threads.
