Torque seems to be the true measurement that matters when it comes to breaking blocks. Anything over 2200 ft lbs to the tire is the playing with fire/danger zone, some hold till 2400, some will handle a brief gear change spike to 2800 for a split second, but generally 2200 sustained is a good rule of thumb max limit. If you run a monster turbo system that spools late you can make almost 2000 HP on a wet block. However, once that turbo system is spooled up and you shift gears at the track and it pulls the rpm range down while keeping the turbos lit, it's easy to spike the torque(cylinder pressure) and destroy the block. This is why pullers really struggle with breaking blocks because that evil sled pulls them down into the danger zone at the end of the track. On a drag truck, you can control your shift points and keep the engine out of the danger zone. In pulling you can't do that unless you purposely run a gear ratio that keeps rpm high and you miss out on the true potential of the engine combination. I don't think you'll be able to keep a 488 single lit to a low enough rpm to make enough torque to hurt the block. I'd run that as a single on a wet block drag truck and not worry about it. This is just my opinion, others will likely have different opinions.
