Advice on stroker build with cracked cylinder

I built a 440 ci out of a 400 block (4.185" x 4") in 2014 EMC using 8 Melling HP sleeves with the flange (step) at the top. That engine had something like .280"-.300" wall thickness-LOL it made a lot of power very very easily. Then in 2016 I wanted to compete in the 2016 EMC in the big block SPEC class (470 ci). Made a sleeve puller -pulled all 8 sleeves out of the same block-bored and installed 8 sleeves for a 4.32" bore--Made a lot of power (696 hp) finished 3rd and is running in some kids '69 Satellite that he says is "crazy". So that is 16 sleeves in the same block. Sleeve it and forget it. J.Rob
