The new RA EJ257 stock short blocks have been known to hold up 550whp so far. Definite improvement over the previous short blocks, but the EJ257 SB really only had issues on bad tunes (below 450whp) or failing when the oil runs low. So in comparison, the FA is still not better than the EJ due to rods failing at a lower hps.
