25ft pounds is too much IMO. Mike



Remember this is a Big Block with the 3/8" bolts not the small block with the 5/16" bolts. 25 ft lbs on a 3/8" bolt isnt extreme. Small block grade 5 5/16" bolts would probably be stretching at 25 lbs.

And for typo's in FSM, for fun if you got one, look up the torque specs for a small block rocker shaft bolt in the 1969 Plymouth manual. It says 40 ft lbs! I'd like to see you get a 5/16" grade 5 bolt evan close to that before it breaks in half. 20 lbs on them scares me that they are stretching.
