Torque settings for Runners needed please
Hi;
The Haynes manual I have doesn't seem to list what I need, which is;
Torque settings for Runners to intake manifold
&
Torque settings for Runners to plenum, both for my '85.
I'm guessing they'll be in the vicinity of anywhere from 15 - 25lbf
...I doubt they'd say 30flb for this application.

To be honest, the key here is consistancy.

Anyone else have the factory settings?

JUST to be MORE precise; My runners are STOCK '85 ones and they're going into STOCK '85 Inlet manifold.
Might take a closer look at the Haynes manual...

There is absolutely zero difference between 85 and 90 plenum/runners as far as fastening goes. The only difference you'll find is that the intake manifold itself the bolts are at a different angle, the cold start valve does not exist, and there is no rear coolant line. If anything I'd more trust the later #s since '85 was a "first year" engine.
