Pontiac Repair: 68 Pontiac Le Mans, motor pontiac, torque specs
QuestionI am changing the motor (pontiac 350) out in my Le Mans and I need to switch out the intake manifold from one motor to the other. I need to know the sequence for removing the bolts and putting them back so that i don't do any damage. Torque specs for the intake manifold would also be great. Thank you, wish me luck....
AnswerHi there:
here is what I found. my on line manulas only go back to 1982 so I did some searching for you. take a look here.

the tightening sequence is this taking the old one off in a circle from outter bolts to inner bolts. to put the new one on. in a circle from the center out. I would split the torque in half and di it 2X first 20 ft lbs. then go it again at 40 ft. lbs. that way the gasket will seat unformly. good luck :)
