no, it's a list of how tight the bolts for a particular item need to be when you are re-assembling an engine

tims3.8stang · August 20th, 2007, 09:44 PM

this was not the right place to post this. this is talking about how much torque you need to put on bolts on the car, not how much torque youre putting out
