Advice on stroker build with cracked cylinder

Negative. These blocks just are not worth all the trouble. They are a dime a dozen.
if u can find one around here , they want big bucks for them, and not many either.

I was told by a long time and fairly successful superstock racer, that a trick was to sleeve all cylinders in a new build.

I spent my whole 1 week vacation one summer pinning the hemi block, where I forgot to drain the block the previous winter, it and the two sleeves in 5 and 7 cyldrs, are still holding up today in a street car.
