Nobody has actually found a hard limit on a Magnum block at all that I'm aware of.



Not looking for a failure point, more so a level where splitting a cylinder wouldn't be a worry.



What are your goals, then?

I'm running a stroked 318 magnum at a bit less than 500 on a regular basis, and I sprayed a 175 shot at it for about 50 passes when it was in my truck. It's now living happily in my a-body and getting ready to race more this season.
