I've been trying to find a definitive answer on the strength of 03-04 WAP blocks and it seems like no one has a real solid answer. Whats the furthest anyone has pushed them and whats the soonest anyone's had them fail? I am looking to build an engine that can handle at least 750hp (probably never going to try and push it that high but I like knowing I can) and it would be nice not having to buy a teksid.
