Upper Intake torque specs
 

1997 Blazer. I am in the process of replacing my fuel spider, and was wondering if anyone could tell me what the torque specs are for the upper intake manifold, as well as the sequence. I searched the forums and found a nice writup on the old CPI engines, and found conflicting data on the torque for the upper intake, I saw in one place it was 44, then 80, and another said 44 then 88. Could someone with a haynes or chiltons, confirm for me what the values and sequence are? Thanks.

44in-lbs first pass
88in-lbs final pass

Order is not given in my references, but I would work your way around going from side to side in a criss-cross pattern. The torque is really light so you really don't have to worry too much about the sequence.

Thanks. I just finished up the fuel spider MFI conversion, and it runs great. While I was waiting for the unit to ship from amazon, I did a heater core swap, and that seems to be working as well. Thanks for the help.
