I have another question on the 91 6.2. Does the cam have a lobe for the mechanical lift pump. The plate and gasket is in place but this motor was originally designed with a electric lift pump. Can I put the mechanical pump from my 87' motor on it? Also, does the mechanical vac pump just go in place of the sensor that is mounted on the rear on this motor? I believe it will but just asking.
Thanks, Ted

I replaced the engine in my 1982 GMC 6.2 with a 1992 6.2. I used all of the orginal parts from the 82. Everything fit without any problems. The vacuum pump will fit in the same place as on the old engine.
