Not really.

A sonic tester would be able to perform the checks to see whether a particular casting might be able to handle the requisite scalloping of the cylinders without damaging the block, but for the most part it's best to keep the HRs in 427 blocks.

If you feel daring, and are lucky, and the sonic results suggest there is some thick cylinder wall to play with, it might work. Still, the HR really shines at the higher RPMS, and you should also have crossbolts to help contain the extra stresses.
