Hi everyone. If you have a completely stock '71 400 engine, how do you adjust the valves/lifters?? The book calls for 20 lbs. of torque on the rocker nut, but does this have to be with the lifter on the base circle of the cam?? Or do you just tighten down to that torque requirement regardless of where anything is?? I put a Lunati Voodoo cam in my engine and put everything back together and the motor runs well. Now I'm hearing something different about where the lifter should be on the cam when torquing. From what I recall, I might have been close to running out of threads about the same time I reached the 20 lbs. of torque. Guess it seemed right to me. Thanks, Nicholas.
