Let me start by saying that I'm an armchair mechanic and have not done anything bigger than a brake rebuild , a timing chain change and a clutch exchange (all on an ancient BMW 2002), so forgive me my ignorance. I saw on speedvision the other day a show where a couple of guys were rebuilding an engine and they were not torqueing the studs but rather were using special studs that they measured lenghtwise to get the proper tightness. they said it was much better than torqueing and I think they said its the way high stress (i.e. drag racing) engines are built. I have never hear of that before. Is it new or am I just not in the loop?
