Some of these were fully rebuilt boxes, lots of money spent on them. They are just not as strong as a Muncie. They are good boxes but not near to the M22 muncie's strength. Toploader is probably on par with a Super T10 which is what GM used once they stopped building hi-po big block muscle cars in the early 70's, perfect for hipo small blocks. ST10 is what was used in A9X race cars (and Group C Camaros too I think).
