    You should make this list a "stickie" at the top of the engine and drivetrain forum so the info will always be easy to find

    I would copy it down but its in every Haynes manual I have ever used. BTW, are those specs for a v8? wouldn't it be the same for my 4.3?

    Yes, they are the same except for the four bolt main info. I don't believe they made a four bolt main block (4.3), but I might be wrong. The only difference in some of the torque spec's is if you build a high-performance motor. Some ARP rod bolts and head bolts require more torque.

    Start in the middle of the intake and work your way out but in a circular motion. The way I do it is, I put the torque wrench on 15 ft lbs and go through the circular motion and then re-adjust the torque wrench to 30 ft lbs and go through the process again.

    Front of the motor

    12..8......3..4......5..9
    11..7......2..1......6..10<back of the motor


    On a side note: make sure you put some pipe dope on the bolt threads so that oil(some of the bolts go into the coolant passages on the heads as well) can not make its way back up the threads of the intake bolt. Plus the pipe dope will slow the corroding process down on the bolts that go into the coolant passages. If you don't, those bolts will start to rust and the threads will corrode or rust away.

    Are the torque specs any different for the intake bolts when running Vortec heads with the Vortec style aluminum intake manifold?

    hum, me and my freind put his 383 together today and torqued everything a little more then those specs... we were using a book called "Hot to Hotrod your Smallblock Chevy" or something like that as a referance.

    Those are torque specifications from a stock stand point. Basic settings, a starting point to get you going in the right direction. Different companies require more. But you get the point.
