Hey,  you guys have all been a big help in past.
Im looking for a video or link  to step by step instructions (pdf) for replacing my water pump on a 454 big block 73-87 chevy c20 camper special. everything is stock .
i see a lot of you tube videos for c10 350 small blocks online but i dont see any 454 big block videos. 
can someone post a link to a video or a mechanics manual for a replacement of the water pump? 
would be lots of help as i learn better from video than anything. 
i have done basic maintenance like replace alternator and starter in the past as well as belts changed. im hoping i can do this myself without any problems. let me know if i will need any special tools etc.  
i noticed it says to tighten all bolts to 30lbs torque..
thanks
